Modern Vespa

Hi guys. I'm swoping an engine around in a Vespa ET2 and found a wire going to the carb. The engine I took out is a 2003 the engine I'm putting in is a 2011. The carb on the old engine doesn't have that wire going to it. Do I put the old carb on the 2011 engine or can I use the carb what's on it.

I'd hazard a guess that the wire you're indicating is for the carburetor heater. I have something similar in my LX150. You can follow it back and disconnect it from your wiring harness when you remove the carburetor.

That's the warmer. Helps with cold morning fuel atomization. You can live without it.

Don't mix carbs. Keep them together with their motor/intake manifold.

it's on the engine I'm putting in. The engine I'm taking out don't have one.

There's no hole to block if I remove it. Or she'll I leave it on.

You can leave it open if you want. The hole that the warmer goes into doesn't go through the carb. Just into it.

Or leave it installed and disconnected at the wires.

Same result.

Thanks guy's problem solved.

Interesting.

Does it do the same job as this thing on the older engines?

it's ok now I know what it is. The plug what heats up the carb.

Sure looks like it!

Is that photo of the later ET2s. Never see seen that before. Are they known to get too cold in winter and cut out.

That's a 2001 in the photo.

It's basically a tube that goes from the engine cowl towards the carb - blows warm air over it. The system works like pointing a hair dryer up your jacket. 😂 I thought it was to prevent icing in winter.

The jacket (that goes over the carb) is missing in that pic - I still have it in a box somewhere…

both engines I've got haven't got one. Do I need to get one and the cover for the carb.

I've run my ET2 without the cover/jacket - but I've not been out in freezing conditions. If there's a frost (or salt on the roads), I tend not to ride - don't want to have an off, neither do I want my bike to turn into a rust heap.

Someone else might be able to comment on what happens when the carb ices up (does the throttle slide stick?).

Your replacement engine at least has space for an electronic one - you can always wire it in if you need it I suppose. 👍

I haven't started on the carb yet I will tomorrow. The throttle cable has been cut so I will add my cable. I disconnected the throttle cable from the other engine with the slid on. Not sure if the slid will fit yet till I see if carb is the same as my other carb what on the engine I took out. If not il just add my cable to the one what's in. Today I swopped the starter motor and stand from the engine I took out because they are both new and then bolted the engine in and connected the electrics. Tomorrow I should have it all finished. See what the weather is like. I'm not working out side but I like to have the doors opened so I can see better.

All done the engine is running. all good now i hope .
I havent test rid it yet but i will in the week. thank you for the help guys

Result. Hope it rides well. 🛵💨

Congratulations shepys, well done!
