Good evening, I have a boat with twin 454 Crusaders that I can’t seem to figure out my idle issue. I have been dealing with it for about a year now.
The starboard engine starts fine and it will idle, although it has a flutter, and seems to idle higher than my port motor. The issue I am having is it has a flutter and then when I run to go fishing, I will run about 3k rpm and it does fine, and then I slowly back off the throttles and it will stick between like 1300-2000rpm, depending on the day. I just the motor off, and immediately start it back up and then it idles back down at its normal idle and still has a flutter.
I have had 2 different carbs rebuilt (Rochester Qjets), replaced plugs, wires, and distributor. I am at a loss and can’t seem to figure it out.
Any and all advice would be appreciated, thank you!
