*This carburetor does not work in High Altitudes due to having the jet needle stationary.
This is 4 th carb best Have to lean out to about 65 jet for near Chicago Il.
The stock carburettor seems to work better
Tried it out seemed good at low speed, but waiting on jet kit, way too rich. Will let you know after re-jetting.
My stock carb leaked, this one doesn’t. Be sure to remove the elbow bend before installing the throttle cable or it won’t work.
This little carb woke my motor up nicely. Easy install. Choke release is a nice feature.
