Any Ideas

[SIERRASDADDY1217]

I got a 81 chrysler 55 hp and it wont stay running and the carbs are rebuilt.if motor is choked it will fire but as soon as choke is off it stalls out.sometimes it will stay running and then shut off.if i can get it running it will stay running if i keep throtle open but as soon as i let off it shuts off.any ideas would help please.

Re: Any Ideas

Does it backfire at all? It sounds like you may have an intake air leak.

Check your vacuum lines, cracked , loose or even one thats just fell of can cause this too.

no it does not back fire.i have a duel card 2 stroke i dont see any vac lines where should they be?it will sit and run on the warm start up then all of a sudden it will`just shut off.but it takes a while to get it to start.im having trouble in the lower idle of the deal.so you may be right about a intake leak.
