I got another problem. For some strange reason I think my tach is off.
Any of you EE types have any suggestions for making a cheap tach
that will work with mags? Preferably digital.

I am not an EE type (whatever that is) but:
How did you determine that it was off? and by how much?

EE = electrical engineer. 

Well it won't go over about 2200 RPM.
Never the less the airplane takes off and climbs out smartly. 
The performance is excellent and the engine is much smoother than
my old O-470 because it has four dynamic balancers on
the crankshaft instead of only two.

Now it could be that my prop governor fine pitch setting is off. 
Or it could be there is something wrong in the intake system as I don't 
seem to be getting full manifold pressure either. I am still in the 
trouble shooting stage after I installed the new engine in the C182.
Perhaps the throttle cable is bottoming out before the throttle
is wide open. Could be the same problem with the prop governor cable.
