Vacuum check results - general engine condition 120-130

RJ,

I don't know what to think of your vacuum test results, so I'll leave that to others who know more about this stuff, but revving up that much when you let air into the manifold tells me that you are running way too rich. I think I have mentioned this before: I have a little air inlet valve installed in the plug hole on the front face of the manifold on a B18 I'm using as a stationary power source. When I have that engine running at 1200 rpm and I open that valve and the revs go up more than 100 I know I'm running rich and I have to lean out the carbs.
