zip ties will probably last longer than a proper rubber strap anyway.

Me too on the sealed battery.

Also, what do you soak the rubber bits in?

Where did you get the sealed battery I'll be needing one soon.
Amazon - they sell them in a two pack for power stair lifts. Be aware they are spade connections, so the connectors need to be replaced.

This is what I bought the last time. https://www.amazon.com/dp/B075RS2ZLF

303 Aerospace Protectant. My neighbor, who is in the Coast Guard, uses it for all the rubber seals of their dry suits, and the boats.

I've been using it for years and years.

Another Amazon purchase. You can't find it on the shelf...


Good stuff

How do those batteries compare with traditional Vespa batteries in terms of power, longevity etc?

A standard Vespa battery is also 8AH, so pretty similar.

They look to be basically an 8AH deep cycle battery, but they'd probably work just fine as a starter battery, too, if you didn't have to grind the starter on a regular basis.

I actually ordered a pair of them since I need a new battery for my Sprint and want to add one to my GL to improve turn signal & GPS Speedo performance at idle.

They'll arrive on Friday, so I should have a report back over the weekend.

I don't know. I do know I've had one in Ruby for over 2 years and it's working fine. I'm not running heated gear off it or anything.

And I also put one in the Stella a number of months ago and the electric starter is working great still. I haven't put it on a trickle charger or anything, but do run it into town a couple times a week.

Tank cavity cleanup today. The tunnel looks perfect. Now it's ready for a clean tank!


Pretty dirty, and a bit of oil on the tray


Tunnel looks great


Back together and awaiting tank

Thanks Hibbett!

Today I spent some time cleaning the tank. Gravel, gas, and reducer and shake vigorously, for hours.
Then I rinsed and added Evaporust. That's where it's at. We'll see in the morning.


Tanks separated


Oil tank and parts cleaned and ready for reassembly


Shake and bake


Now we wait...

Oil tank tested for leaks. All is good. Also, inside of the tank is good and awaiting a new fuel tap.


Cleaned up nicely

Speaking of the tank cleaning.... because I gotta redo mine. Has anyone used Ospho for the tank to convert the rust and keep it from rusting? Just spit balling here but would there be any drawbacks from using that?

Was planning on doing electrolysis since I did vinegar originally but still have a BUNCH of flakes in there. Noticed it yesterday when I drained the tank to remove it to check grounds. Figured since I have it out completely again may as well go to town on it.

Doing some googling, other than the fact that you're going to have to get any residue out afterwards, there's no chemical reason you couldn't do it.

I'll probably try it with my VBB tank as a final preventative treatment next time I'm doing a gas tank.

Oh I do have that spare tank I got from sdjohn I could try it on that one first and see how it goes. Forgot about the wiping down after. That may be challenging. Might be able to wrap a shirt around a brush and wipe it all out that way. Then blast it with heat to dry.

cut a scotchbrite pad into a circle and affix it to a mandrel, use that on a drill bit extension to scrub it all out, maybe. Like a kinder, gentler version of how I scrubbed the rust out of my GL tank with a wire brush.

good thinking! I also have soft bristle brushes that may work. Gonna look into that tonight. Since I have 2 tanks I'm gonna do electrolysis on one and ospho on the other and compare the results.

Science!

Progress!

I put a fast flow fuel tap, new oil and fuel lines, cleaned the carb, oil pump, and carb box. Now it's time to put it all back together and start it again.

I didn't take a ton of pictures, but here are a couple anyway...


New fast flow fuel tap being tested. It works great!


Carb was glued shut. Lots of carb cleaner to get it apart


Then I stuck it in the ultrasonic cleaner for a good long while. It bubbled a lot...


Clean carb, vready to be rinsed off and out back together


Lots of grime


All cleaned up and put back together


Much better


Inlet to the engine. Pretty dirty


Engine cleaned up. Not perfect, but it'll do.

Hey, qa! I've been away awhile, but this is one of the thread titles that caught my eye right away and I wanted to read it start to finish immediately. Bianca is a fantastic name, kudos to your lovely wife! Such a good saucy Italian moniker and perfectly descriptive of her og paint. Which polished up very nicely, btw, nice work, Scott!

Congratulations on your new scoot. I'm enjoying your progress and great pics as usual. Especially satisfying to see the cleanup of the tank cavity. Spic and Span!

Is that some sort of spacer or just an uber-thick gasket between the intake and the airbox in the photo above?

Any idea what purpose it served? I assume there has to be one. My P200 motor didn't have that, but it also had the 24/24 carb.

You see them on old cars too, I think carb icing or vapor lock is what they're working to fix but I don't really know.

It was typically used as an insulator against heat from the manifold. Don't really see the need for it on the Vespa.

I'll bet someone added it because they thought it was needed. Not a factory gasket.

Thanks K - good to hear from you! I'm glad you got out riding Blue, and great job on clearing out the idle jet. I clear mine out many times a year. That jet specifically.

I'm excited to get this baby on the road and up to Yachats!

Yes, that is a spacer under the carb box. It's got a 24/24 in it. I was wondering if it was needed also. I'd rather not if not necessary. I plan on checking the oil gear that goes into the pump and engine. Maybe it's there to give some clearance? Hmmm


Check out the solidified oil on the gasket. The groove in the carb box was all gooped up

Ok, we just got back from a week up the coast at Nehalem State Park, just outside of Manzanita, Oregon. Cute little coastal town with a road that runs right along the beach for a couple miles.

We'd park the rig along that road and have a day watching the waves, water, beach goers, cribbage games, food, and sunsets. Oh, and the storms! A bitchen time and lots of R&R.

But I digress, this is about Bianca and her progress after all, which I got a few minutes in today.

I flowed the carb box to the engine and the carb, and installed them both. Tomorrow I'll hook up the fuel and oil line, fill her up, and give her a gentle kick.

On with the pics...


Our parking spot for the day


Beautiful sunsets from our rig


Coffee and muffin to help get the ball rolling. Not nearly as tasty as banana bread... The floorboard is gonna need some work...


This is the engine inlet


And the carb box. I put the carb box on the engine and scribed a line where to Dremel. See how much I need to open the bott of the carb box?


So I picked a good grinding bit, took a swig of coffee, and started grinding...


Ok, pretty close. Time to break out he sanding wheel, then 120 grit polishing pad


Pretty good - not perfect, but pretty good


BTW, these are the grinding bits I have. I used the 2nd from the left


And these are the polishing wheels, each color a different grit


The gasket fits nicely. Just dry fitting everything to endure everything lines up properly


This is the oil pump gear. I cleaned the teeth and corkscrew channel. The carb box fits fine without the spacer


Box and carb installed. Just a few things to hook up and it's go time.

Progress, but not running right. Here is the low down...

I got it running but it wouldn't idle. Recleaned the carb and wired the jets. No change. Then it dawned on me to put the carb in when it was running good. Still no change. Hmmmm

So I took a peek at the wiring going into the CDI and also the plug wire and... Nothing. It wouldn't start at all. Hmmm

I cut the ends off both ends of the plug wire, reconnected the wire to the CDI and plug cap. Nothing.

Cleaned the wires going into the CDI and made sure they were tight. Still nothing.

Checked for spark by pulling the plug (and checking with a spare plug) and grounding it to the shroud. No blue spark when I kicked it over

Pulled the green wire - still nothing.

So tomorrow I'll put in a new CDI and see if that remedies the no spark situation.

On a positive note, the little air bubble in the oil line worked it's way into the autolube mechanism, so that looks like it's working properly I'll take the win...


All ready to kick it over. I've got premix in the tank until I can verify the autolube is working, which it is...


I'm gonna try this tomorrow.

Man, qa, you are livin' the DREAM with your RV parked right there on the beach, watching the sunset!!!

It's my dream, too, and I am completely JELLY!

Beautiful pics and so glad you got to enjoy a relaxing week away together.

Bianca has the cleanest under-cowl I've ever seen. Good luck finding her spark!

(the chocolate muffin does look good, but.... )

Thanks K - the muffin was... ok ... Not banana bread though... Sigh....

So I need the brain trusts help to see if I'm on the right track.

I think I've got a fly side air leak, but I'd love some other opinions. Here is what I know so far...

I changed the CDI and got back spark! Yay.

While cleaning this up, I took the flywheel shroud off and it was filthy, as is the air passage area. I've never seen that area that dirty on the handful of scooters I've worked on.

I got it started and running, but just kind of. What I mean is i would rev it up and the revs would drop down slowly towards idle, then want to die, whereas I could get it back up by feathering the throttle, or adding a little choke.

Waaaannnnnnnnnnnnnnnggggggghhhhhhhhg vs
Waaannnggghhh

But it is all inconsistent. A number of times it revved out of control and I had to turn it off. No throttle at all, and I'm looking at the carb so no stuck throttle.

Once it was good and warm, it would idle, but seemingly wanting to take off, and drop down from revving slowly.

I swapped to a good known carb, good known jets, so I can eliminate that.

The gear oil is clean, no gas in it so I'm assuming the clutch side seal is holding.

So in conclusion, I'm going to pull the flywheel off and see if it's a mess in there. If it is, ill bypass the pressure test and go for rebuild. If it's not a mess, a pressure test is what I'm thinking of doing next.

What do y'all think? Fly side seal leak? Any other ideas?


Caked on grime


That's better...


New CDI - pretty...

Was there visible oil around or dripping down from the fly side seal? If not, then you don't have a fly side leak, though it sounds like you have some sort of air leak.

I'd start with the pressure test, even if you're just itching to split the cases. That way you'll know if you should be looking for a leak or not.

And I'm going to guess that oil inside the fan shroud is leakage around your exhaust--is it nice n' clean and well-sealed? If not, that's where I'd start, especially if the pressure test passes.

Chris came over today and we proceeded to pressure test the engine. The carb box was loose! So we tightened it down and gave it another shot of running.

Chris fiddled with it for a while. Same issues happening, all signs point to an air leak.

It dawned on me - the air breather on the clutch cover was just a bump of grime. I'm sure it was blocking any air flow.

So tomorrow I'll do a pressure test and check the gear oil and see if it has gas in it now. It didn't when we first changed it, but the air breather was clogged up though.

We shall see...


Pulled out a bunch of plant matter out of the fins before realizing I should have taken a picture...

I use super clean (purple bottle) for all my heavy duty degreasing and cleaning, it completely destroyed any traces of dirt, grease, grime almost on touch. I like your plan with the metal brush on the stick, I have been very lucky and I never had a scooter tank look bad, just a small flake of metal once in a while but nothing more.

They also sell metal bushes that the handle can bend , sort of a old metal hanger for clothes, that works too in case your brush metal and stick doesn't reach out some corners. Looking good so far.

I hooked up the handy-dandy pressure gauge and it wouldn't hold any air.

I blocked off the clutch cover vent. Still blowing out air like the hose wasn't attached. A big air leak.

Next I pulled off the flywheel to inspect and get a better listen to what's happening. Bingo. The seal is disintegrating so bad that the spring was sticking out.

Suffice to say - the leak has been found.


Pressure tester hooked up. But what's that around the seal?


Yikes


A chunk of spring I pulled out


Someone was in here in 89


Stator wires looking crusty. No surprise. I'll rebuild it while it's out

No oil leaking from the seal - it was all blowback, as you thought. Thanks for the feedback!

It's decision time.

1. Replace the seal
OR
2. Get a bigger ball and pump it faster.
