Hi there,

You give us very little to go on.

What year bike is it?

Is the petrol tank vent fitted correctly, eg: you can blow air into the tank. Is the petrol tap clear of obstructions.

Are you running 50:1 fuel/oil ratio (or similar)

Have you cleaned out the carb very thoroughly, including removing the emulsion tube, pilot screw, pilot jet and then blowing through the passage ways?

If the carb is thoroughly clean, and you still need the choke to start when warm, and the bike is getting on a bit, then the mag side crankshaft oil seal may have failed.

Best to provide us with a few more details.

Bye, PeterB.
