<<I just finished redoing the heads and adjusting the values on my 85
Westy. It starts right up and appears to have good horse power. However,
it is running very rich.
I checked it for vacuum leaks. Also, connected/disconnected a new O2
sensor but it doesn't change a thing. � Could it be that a valve isn't
adjusted correctly? Someone mentioned that I should adjust the air
box.>>

Check & adjust the TPS
