Long time lurker.
So I’m banging my head against the wall.
49cc agility bogs at full throttle
120 psi compression
Valves adjusted .003 in, .004 ex
Kicks over and starts right up also starts up easily with battery
Cleaned carb twice. Still bogs. Then I put a new Chinese carb. Sounded exactly same as kymco carb.
Tried 2 different cdis. Sounds exactly the same.
Have sprayed for air leaks. Found none.
Tried revving with exhaust off. Still bogs at wot.
Petcock tested great. Gas is fresh. Oil level is perfect.
Stator is putting out 13.8 volts if I recall.
Tried 2 different coils. Still bogs.
Plug looked very new.
Anyone ideas are welcome!
