Re: Carb leaking?
!stford,
What may be occurring is ,when the motor is running, fuel is seeping past the throttle bores
and over time soaking the bowl to base gasket. This can occur when the bottom face of the bowl is not truly flat. It is not uncommon ,even with a NOS bowl, to have a low area
in the center of the bowls' bottom face. I mill this face and usually find from .005 to .015 out of flat and usually where the vac chamber and throttle bores intersect.
My short cut to check for a loose throttle shaft ( about 80 % effective ) is
to adjust the brass mixture screws. If turning them in causes the motor to stumble or quit most likely the shaft fit to the base is OK.....OMHO.
If it's running good aside from the little leak leave it alone....all flatheads leak at least one kind the fluid.
