New member here and a little stumped. model j150gledb. Earlier last fall the motor started a random misfire. Only intermittent, some times on take off, other times at around 46-4800 RPM. Sometimes it would not do it at all. Fast forward to a few weeks ago. I replaced the powerpack, coils, plug wire and optical sensor. All CDI and the recommended Champion plugs. Ran great the first few times out then the next time out it ran great the first run and did not start again. I got towed to the ramp and when i got home the dang thing wouldn't not fire, started right up every time. I went out again this past weekend and same thing-ran fine first run, fished 45 mins or so went to move and no start, no fire. Towed back once again. I checked the kill ckt as i have read about, kill switch lanyard connected. When I got home i put my old powerpack back on, no fire, removed the rectifier and looked ok but the gasket tore. As a last resort i put the old optical sensor back on, inspected the wheel for cracks etc and looked ok. Hit the key and she fired up, of course cant tell much on the muffs other than it runs. Had a tournament yesterday and braved it. It never failed too start but runs like crap, like missing a cylinder. compression test reading 120 psi in all holes. As the day went on it never ran better but never got worse. I also noticed it wasnt charging as normal, usually around 14v and yesterday all i could muster was 4300 rpm and only "charging" at 12.2v. At idle it is lower than that. battery terminals tight and clean -no wing nuts- battery stays on a maintainer and load tested ok. My question-is my rectifier crap or when the gasket tore when i removed the rectifier i had some gasket maker and gooped it up good and tightened it down. Could i have caused a ground problem with too much sealer? I dont see any goo running down the block like a stator failure.🤔
