Been lurking... Sounds like you pilot jet is plugged or the passage from the pilot jet is plugged. These are very small and can be plugged very easily. Strip the insulation off of a length of copper wire and pull one strand off. Use it to pass through the pilot jet. Do this to the pilot jet circuit (under the area that the pilot jet is seated). Use lots of spray carb cleaner after the wire and do it again. Watch for spray cleaner to shot through the small hole that is in the carb bore (angled hole on the engine side of the slide). This should solve your problem... IF it is the carb. Engine seal behind the mag will be your next place to check. Do the pilot first

Carb cleaner tool

Recently I've been rebuilding two old abandoned bikes. A great tool for cleaning the small orifices on a carb is a hypodermic needle. I've got a couple 2" 26 gauge that work great. Rigid enough to clean just about any small clogged opening.

That was it, a clogged passage. Thanks for the help every one. All it needs now is fine tuning. One last question, the manual says to set the air screw 1 1/2 turns off the bottom and ajust. Witch way increases or richens the engine ?

Clockwise is richer.

Everything you ever wanted to know about carb tuning.
