2004 predator 90 not running right after repairs. help please.
Hi my name is drew. I am a new owner of a 2004 polaris predator 90.
I bought it off a friend of mine. his son road the wheels off it. I got it
for a great price. I bought it not running. My buddy seemed to think it need
rings. being 2 stroke and the fact that they were the original owners of the bike
and they had never done that I agreed. So here is were I'm at:
I pulled the jug off found the rings shot. The cylinder wall was fine.
I bought a new Wiseco piston set and had the oem cylinder bored to fit the new piston.
-after all that it would not run.
I called my buddy. he said the atv had been sitting in his shed for the past 3 years .
So I cleaned the fuel tank out (which it was bone dry when I bought it).
I pulled the carb apart and it was clean.
I also was not sure if the oil pump was working so I premixed the fuel.
-after that it still would not run.
I then checked the crank seals. I found one leaking and the fine.
So I replaced both crank seals.
I pulled the carb back apart and rechecked everything.
-After all that it would run (rough) but shut off abuptly.
I would put my hand over the carb and it would run rough, take my hand off the carb it
would take off like a jet and then shut off abruptly.
It seemed like it was running lean so I put a larger jet. It ran a little better
but still after a little it shut off abruptly. so I pulled the jug back off to check
to make sure I installed the piston and rings right and found nothing wrong.
So I'm stumped and looking for help. I can easily throw a complete new carb at it for $60
off ebay. I could easily throw a coil, stator for $80 off ebay. but I can't seem to find anything
wrong with either of those. HELP!!! PLEASE!!! there has to be something I'm missing.
