Hey guys,

I'm pretty new round here so I'll do my best to explain myself!

So I've started to derestrict my 2004 Vespa ET2 50. However, I'm having some trouble finding the right size for a new main jet for the carb, as it appears to depend on which country the Vespa is built for and the size of the carb etc. I'm in the UK, and everything on my scoot is stock (for now!) and the current jet is 86.

Can anyone help?

I don't know much about the 2 stroke ET2, but from the little bit of reading I've been doing the Uk version should have a Dellorto carb, and an 86 jet sounds way too big for a stock carb. Are you sure it hasn't been upsized already?

I am not sure, but in my Dell'orto as far as I remember there is 72.

I've got an LX50 2t with the Del carb and in the U.K.

Up to a certain year it was 58, then went up to 63 stock.

I'm running a 70cc cylinder on mine now and have a 71 in there and that's on the rich side (don't want a seaze up).

So yeh could be wrong but an 80+ sounds way too high

Also bud there's a couple of great Facebook pages here in the U.K.

Ones solely for ET's and one ET's and LX's

If you have the Dell'Orto PHVA carb (the stock ET2 carb in the UK), an 86 is waaaaaay too rich for a stock ET2. I'd suggest getting a jet kit in the 50-72 range and plug chopping until you get a good result.

Scooterpartsco.com in the US sells them: https://scooterpartsco.com/carburetors/jet-kit-for-dellorto-phbh-phbl-phva-phvb-vhs-p-10458

I believe SIP-scootershop.com also sells them but their website doesn't like to load on my work computer. Just make sure you get the jets for the right carb. Yours should be the PHVA.
