[walleye1963]

Hi guys.I just put on a 72cc bbk.carb is a 20mm I got from 02starrider.it has a 85 main jet.it kind of hard to start at first have to give it gas or it will stall out I set the a/f mix .but once the hi idle kicks in its good.but once it cools off I have to give it gas again to get it started.anyone no what could course this? Do's it maybe need a bigger jet? this carb takes the 5mm jets.02starrider says it sells a 3jet kit for it .it has 90/95/100.for $7.99 free s&h.any help would be great.thanks guys.

Did you plug back the auto enricher?

Yes I did.as a matter of fact it acts funny to.it will rev hi then go down to were it almost stalls out but will catch itself and rev hi again it do's that until it warms up.then it will idle good.it only do's it with this 20mm carb .the stock carb just do'st have the gitty up and go like the 20mm.
