Fellow boater has almost pulled all his hair out last couple days. He rebuilt the Q-Jet from one of the 454 Mercruiser engines on his boat. I kept telling him to send it to a knowledgeable carb. guy & have it done right. I'm not a carb. guy myself & will be the first to admit it.o No: Anyone in the LA area able to look at a carb. for this fellow? He can get it off & deliver or leave it on to set up the mixtures. Cheers, Steve Craig, PS. he's boating year round & we are still looking at late April before the rivers open up.
