All Plugs Fouling on Right Bank
Thanks to all your replies. First chance in two weekends to mess with this.
Engine is pulling 15 to 15 1/2 lbs vacuum at idle. I reset the valve lash after breaking in the engine. I have set the timing with the vacuum hooked various times between 32 and 38*.
I checked the floats, they were 8/32", I moved them to 9/32 (spec is 7/32"). I also have the float drop set to 3/4" like the factory manual shows.
The engine still idles noticeably rough, idling around 850 warm. I see the primary butterfly is not completely open, held a little closed by the heat thermostat in the intake manifold (see picture). It clears up a little when I pull the choke fully open (see the second pic). Maybe the choke thermostat is not pulling the butterfly fully open??What should be the normal position of the choke butterfly after full warm up?
