She runs but not good. Cleaned carbs, set points and what not. Great Spark Great compression. will not run wihtout the choke. IF you take the choke off motor speeds up and goes to quit. until you choke it again. Maybe fuel pump? Anyone know of anything else i can check. Maybe fuel filter? Seems to get ok fuel but maybe not enough i took the fuel lines off the carbs and pulled it, it shot fuel pretty far. and what not. But im still not sure. oh well maybe if anyone has any ideas let me know. This thing is royally pissin me off :confused: :confused: :confused:

Could be the seals,needle to low in the main jet ,main or other jets clogged,ice in the gas could be quite a few things-Hope you get it though I used to have a 250 polaris single & had a blast on it.

I'd take a close look at the crank seals....sounds kind of like she's pulling air.
