[QUOTE="SRAD97750, post: 209069, member: 425"] I would -Clean the petcock and lines -Get a compression # in psi, with the carburetor off -Test the carburetor for internal fuel height. Carburetor inlet hooked up to the tank. With a clear tube from the bowl drain, open the bowl drain and keep the other end of the clear tube open and above the carburetor. The level in the tube next to the bowl is the same as in the bowl. -Purge the crankcase of fuel. Fully kick it 10 times with the carburetor off. When my 89 YZ250 would flood you had to pull start it after, for near a football field before it would clear up. A larger 2t deserves an inspection every 50 Hrs. Minimum. Smaller ones every 25 hrs. I pull the cylinder and piston every inspection and check the "Big 5" measurements. Gasket kits are cheap, you learn alot about 2Ts the first time you tear them apart for inspection. Inspection is cheap insurance against a failure while on the track/trail. -BIG DAN:thumb: [/QUOTE]
