Ok, I'm back to jetting my carbs and final engine runs before taking the
plane to the airport for assembly.

At 1000 - 1200 RPM I am getting 20 in Hg MAP. Is that normal or should I
look for air leaks (false air) before drilling up the idle (slow) and
main jets?

My own 13B when equipped with a GM Rochester two barrel carb and my homemade intake
manifold gave me a MF reading of less than 15 inchHg at about 800 rpm.

The same 13B now equipped with a Holley throttle body injection system and essentially the
same manifold reads about 14.5inchHg at about 1000 rpm.
I cannot guarantee that I do not have air leaks, but if I do they certainly must be minor
ones.
Cordially, Yvon Cournoyer

Please! Short lines guys or you get this type of mess.
