Modern Vespa

Hey there all. I have a VNA engine and the carb I removed says: UA16S1
Can anyone tell me anything about this carb, or where to find rebuild kit? Thanks.

Actually, that's Rover Eric (PM here http://www.modernvespa.com/forum/privmsg.php?mode=post&u=2654

Eric knows his stuff and can certainly help. Max at MotorSport Scooters (http://www.scooterwest.com) is also a wealth of knowledge and can sell you the parts you need.

Its a Dellorto UA16S1 carb for a piston ported VNA. Hard to find parts for or find replacement carbs.

Has 1 gasket for the float bowl and 2 gaskets for the banjo.

Look after that carb carefully and treat it as if it were made of eggshell

cool, now we know the lady knows her stuff as well. Plus she a sponsor, good to know if and when I ever get that rally junk running.



Props my sista

Yup yup. You can find spares for it ..but only off of people throwing away / parting out VNA engines. It only ever went onto that 1 model scooter, and only for a couple production years ( if that ).

It's probably closest resembling the GS150 carb.

...

Go to EUROCARB LTD. - they have the greatest inventory of Dellorto parts in the world (since 1968 - 40 yrs.)! They ship promptly to the US - I have used them for the past 15 yrs. - 100% satisfied!

Thanks for all the good direction. You are right about the engine, it's of a VNA2M. 1958 125. It's from my allstate. well, worst case scenario, I try to build some gaskets myself.
Thanks again.

Are we still talking about this carb?

You've had multiple people offer complete ones to you, haven't you? ( i read Tom G's response to you on the BBS )

why are you still trying to find individual parts for this thing when people have offered you a whole new one ?

Thanks for reminding me, I e-mailed Tom.
I may be anal, but I just don't want to spend money that I don't have to.
I'm disabled with not a lot of cash, so I'm trying to do this project smart. But, it's true, I'm too cheap at the same time.
I have the carb and parts that came with it, but not sure of their usability. Thats why I keep asking. Again, you're right, I need to stop thinking of 10 different options and go with one.
Thanks for slapping me back to sense.

I'm not trying to be mean ... it's just like ... you're getting hung up in details.

If you're doing a ground up, nut and bolt sort of deal on this bike, then i can understand trying to make this carb work at all costs - even buying a new one as needed.

Honestly, though, i think you're going to be pretty disappointed with the speed and performance of this engine. It's seriously a dead end.

I would be looking for a later 4-speed VNB or VBB engine to replace the one you have.

Don't get me wrong - the piston ported engine you have is a very SOLID engine, and is reliable, etc... but it's just a complete dog.

You're 100% right...
But in my situation, I can't be too picky.
I got this scoot for $300. Knowing a long and slow process is ahead of me. But I just wanted the steps I take, to be worth while.
If I can get this thing right, even if it's a dog, I'll be very happy. Then, if and when I can, I can be a little more choosy.
And believe me, I appreciate your honesty and advice.

In futhering my point, this carb is kinda hard to get in that it's unusual and not purchasable from a store new, but it's kinda not at the same time.

People tend to NOT run this engine, upgrading to a different one ... and as such there's a crop of these carbs laying around unused.
