"I was having problems with WO
"I was having problems with WOT misses and miss-firing at all RPM ranges. Found the stator to be the problem and replaced it with a new CDI model. That corrected all the problems I am having, well almost. Before I begin, I purchased the boat and motor new in 1987 and it has provided 21 years of outstanding service. It’s a Johnson 150 GT. The stator and a rectifier\regulator are the only major items I have had to replaced, other than regular maintenance.
The engine is running very very rich, but, not fouling any plugs, and smokes very bad with the flusher attached at idle and at the lake, trolling and at idle. This year it has began to smoke more and more. I am running Pennzoil 100% synthetic. All the plugs are wet but not black or carbon. New QL77JC4’s as I have ran for many years. In years past, after switching to synthetic oil, the plugs were dry and clean. It’s firing on all cylinders, 100 to 105 compression, and was decarbed last week. It seems to run ok but is not quite as good as I am use to. It gets to about 4600 RPM’s @ WOT ; 5200 is about normal.
Of course, the VRO comes to mind but I tend to think there may be an air leak in the fuel line or, the likely problem is at the carburetors. I removed the silencer cover and noted gas in the two brass tubes that point towards me. It also looks like a small amount gas is at the bottom of the silencer. I read where this points to needle and seat problems? The carbs have never been rebuilt. I am considering rebuilding the carbs; should the floats be replaced? Are the kits and floats available together or separate?
I like the VRO and my guess it is working ok but that may be wishful thinking. Should my approach be to rebuild the carburetors first, then if the rich condition still prevails, look to the VRO, maybe disconnecting the VRO and going with 50:1 premix?
I’ve read many posts and need some expert direction. Thanks for any assistance.
