'88 3.7 carb issue?

clueless

Member
Hi All-

My engine wants to die when I tip in the throttle. Does it when warm or cold and also does it from low rpm or medium rpm. Basically any time I give it more gas
it wants to stall. If I do it very slowly, it will ramp up just fine, only when I make a more rapid change. I think maybe I just need to rebuild the carb. There's no marking on the carb, how can I tell what type it is?

Distributor is mechanical advance, no vacuum assist.

Thanks Much!
 
Either take a pic and post it or determine if it is a 4 barrel or a two barrel.

No vacuum assist on marine............ever.......
 
99% of the time when a symptom occurrs as you describe it is the accellorator pump has gone bad.

See image attached, Item 31
 
If it has ONE air/fuel mixture screw it is a MERCARB

if it has TWO air/fuel mixture screws it is a Rochester

Cant tell by the picture.
