heres the problem upon first start up after winter storage cannot get the sled to stay running without using the primer to keep it going. though it might be dirty carbs so took them apart cleaned them and the same thing occured. also oil comming of exhaust. did not think it was bad gas because my mxz runs fine. I think it might be a fuel pump gone bad. need help and snow.  p.s ran fine before it was put away  thanks .

You might have mositure on your fuel pump diafram.

Take the fuel pump apart and there is a little plastic thing right in the middle.  That is the diafram.  It looks like a sheet of hard plastic.  If there is moisture on it just clean it and reinstall.  Use all the old gaskets they wont leak. The only reason you probably even got it started was because of the primer.
