Hi, My head gasket now fitted and engine almost running well?
However the carb over flows after about 3 minutes running,I have Tried another needle valve and when stripping there is no visible dirt,Do you think the pump has to much Pressure or maybe its another cause,
Have you checked that the float is sound. Try immersing it in a saucepan of hot water and check for bubbles. Burlen now make floats suitable for modern fuels.
Its fine now,I originally bent the forks down at the top of the float thinking this would be ok but didn't bend far enough,now bent a little more and all is working fine
