Bryan,
I have discovered that the port sat the bottom provides vacuum to the
power-vavle. This is the spring loaded diaphram located above the float
chamber in the top half of the body. Vacuum cause the valve to open and
lean out the mixture. At full throttle, vacuum is supposed to drop and the
valve closes. Enriching the mixture.
I am wondering if my spring is to week, so the diaphram remains open at all
times.
I have to back the mixture needle all most all the way out and have the idle
screw turned almost all the way in to get the thing to idle, and it only
idles at 1100rpms. Any less and it dies.
