Got a pit pro 125 wont run it has good spark good compression
And cleanded carb and tank new plug new fuel fires ocassionaly
But wont run ocassionaly coughs bak thru carby
So got fuel and spark but wont run any ideas pls

blocked pilot jet would be the first place i would look at.

and it may be worth checking for vacuum leaks too

then adjust your valves, .003" on the inlet and .004" for the exhaust.

Valve clearance and timing thanks again

timing wont be adjustable, unless it has an adjustable outer rotor set up on it.
