1991 Fastrike 150hp serial # G02956027 rough idle and lately seems to be loading up at low rpm's had a compression check done all between 85 and 90 a little low but was told that it is still got plenty of hours to go WOT is great 60mph by gps doesn't skip a beat but low end she isn't as fast out of the hole and it bogs when puttin it on the trailer and seems to be a little rich .plugs where wet 3 of them when pulled.What do you think I should try one guy mentioned a gasket on the side of the carb under a plate with 4 screws that might cure it >>> help

Re: low idle problems 1991 fastrike

do you have a spark that will jump a 7/16 gap?

most idle probs that i have seen are due to poor comp, dirty carbs, or weak spark, but not all.

you cannot just pull the hood off and look at the carb and say "well shes clean"... you may be able to clean them and reuse the old gaskets if you are carefull but you are better off to rebuild when you clean them...ive cleaned and not rebuilt a few but when and if i do i cant gaurantee there wont be any leaks.

it doesnt take much to plug those little orifices. ive pulled them apart and they look slick as a whistle but a good cleaning solved most of the idle probs ive encountered.

how does your reed valves look?
