yx 140 no power above 20% throttle

Recommended Posts

Hi guys I have a wpb race 140, yx 140 engine.

 

Was out a few weeks ago and chain came off, smashed through casing and tore stator apart.

 

I have replaced the stator but now anything above about 20-30% of throttle there is just no power, it's like I rev to about 20%, power is normal anything above that and it's moving at like walking pace. Same goes for all gears, I hit about 20% throttle and it's running fine but anything above and it just can't pick up the speed.

Sounds like your primary jet is clogged. If it's idling fine, your pilot is getting fuel flowing through, but as the needle lifts in the primary, fuel isn't passing through in higher volumes. Pull your carb off and pull the large jet in the center that the needle seats in. Make sure it's clear through the center AND the holes through the sides.
