I have searched, researched, studied, fought and cried. Here is where I’m at this this motor. Bought it on a stand in running condition, needed a foot. Good compression, cranks, idles, everything is a go. I replaced foot, learned all about the gear linkage in that process. I rebuilt water pump at this time also. Motor cranks right up no problems. I take off and it dies down after about 10 mins but still idles. I park on a sand bar for several hours no big deal. Leave sand bar about 10 mins of running motor dies and will not restart. It was not priming, found multiple fuel leaks. I give up and get towed in.
I get it home and over a few weeks I replace fuel lines, new primer bulb, add a water seperator, and go through the fuel system. From carbs to tank, lines are checked tightened or replaced.
I go out every few days and crank the motor, let it run a while, just trying to build my confidence back up. Well I take it out this weekend. Cranks right up, idles/runs fine. I ride about 10-15 min 3/4 throttle and it dies down some, but recovers so I go WOT. At this point it’s been running 20 mins. I make a big turn and start back towards landing and it goes from 1/2 throttle to DEAD. Dead like the kill switch was pulled.
I run to primer bubble, it’s tight. I snatch the cowling off to check the temperature of the heads. I was able to put my hands on them, way cooler than I expected. Motor turns over but will not crank. It took a little over an hour to get help, so I kept trying, no luck. This is about 2:30. I get home get settle and go out and try it. Motor is a little sluggish, but fires up and runs like a champ.
Ive read and talked to a few mechanics that have suggested stator and or power pack. I checked stator 405 ohm yellow brown, 96 ohm orange. I have not pulled fly wheel. I’m trying to justify what my problem is, not just change parts. Any suggestions on what I may have missed or need to dig into?
