Here is a bit of background:
97 SJ with full 62t motor from Yamaha Couch
Bored out Bpipe
Protec C2 Head with 180 PSI Domes
MSD Enhancer
Stock 38's rejette with K&N filters and Outerwears
Ok..Ski was running fantastic the entire summer(running roughly 15 gallons per weekend) until one day I landed it upside down. After this I had to crank quite a bit to get it running. Once it was running it ran awesome....until I went to idle and it just simply died. It would fire back up but didn't want to idle at this point. It finally died and I killed the battery trying to get it started again.
I charged the battery and it fired right back up nearly instantly. I rode it for a bit longer but finally gave up due to similar issues.
It also did a lean runaway out of the water. I attributed this due to a leaky fuel line(colored lines turned brittle). I replaced all of the fuel lines and installed new fuel filter. I also went ahead and pulled the carbs to check them out..found a bit of crud but nothing major. Installed with new gaskets. Reeds looked fine from what I could see and feel.
Now I still have 180 psi(and cylinder walls look like new..just put a new head on so got to check them out), great blue spark and motor is getting fuel(I have a primer installed so have made sure its getting fuel). Ski still wont run worth
. It fires up, sputters and shuts off. The only bad sound it makes is that it seems to crank over fast then make a clunk...then crank over fast and make a clunk. Im thinking the bendix is on its way out from all of the cranking.
So what else could it be? I have never been into the stator on this one and honestly thats about the only thing left that I can think of since everything else has been gone through. Could it maybe have loosened up and turned on its own advancing or retarding the spark? I already pulled the front cover just to make sure nothing was loose in there and everything looked great...of course I couldn't see the stator.
Sorry for the long post here guys...just trying to get this thing ridable for the last big weekend of the summer and its starting seem hopeless:Eyecrazy:
EDIT: Just remembered another symptom...while i was trying to start it in the water it occasionally sorta backfired in the water...it felt like someone was hitting my leg with a hammer.
