Hey all,
I have a 1979 johnson 100hp v4 that is having some issues. Heres the stroy. Last summer it was running however it would only max out at about half throttle and any more throttle it would eat gas and bog and stutter really bad. Sometimes it would have a hard time starting cold and while up to opperating temp. When running on the muffs it always started good and reved up with no problem. When it was under load it would still bog real bad.
Just pulled out of stoarge last weekend and it wont fire. It turns over just fine however no fire. Cleaned the carbs replaced all the vacuum lines and fuel pump and plugs and still no go. Sometimes when I crank it over it back fires and smokes. There is raw fuel in the exhaust so Im guessing its getting fuel. When I was checking for spark I got zapped while holding the plug boot so Im think new boots, wires and coils are needed in the near future. Checked compression and all range between 90-120.
Anyone have any thoughts on why its not running?
