I have a 110 Avanti briage..been sitting a few years but I have it running great. strat easy,idles good and runs strong.only issue I am having is when I put it in 1st gear,unless I give it gas,it chokes out.
any suggestions why?

 

Have you tried raising the idle and or turning the fuel screw out 1/2 a turn? Carb may need cleaning after sitting so long also..

 

complete carb rebuild and is adjusted to idle perfectly and runs great

 

Have you ever adjusted the auto clutch?

 

no. it is a 3 speed semi automatic with reverse

 

It could be dragging/grabbing a little and stalling the engine.. Its a easy adjustment.. there is usually a bolt/nut under a small plate on the clutch cover.. loosen the nut a turn or 2.. screw in the bolt until it hits bottom and back it off 1/2 a turn and then tighten the nut..

 

do this while it is not running? right
this is the bolt?

 

Yes that is it.. adjusted with the engine off..

 

thanks.
I think it may have been tampered with because the cover was off when I got it and the guy said it needed a clutch and gave me a new one.but we have it running and it shifts fine

 

Try adjusting it first and if that doesnt help it may need the new clutch.. Id think the adjustment should help.. have you changed the engine oil?
