Hi Jon;
If you have installed intake drains without re-inforcing the thin wall
tubing at the drain boss there is a possibility of crack development around
the boss.
I do not know if this is the problem but it certainly is a candidate. Check
it out.

Subject: Yak-List: Carb swap, manifold pressure oddness
Finally got my stock CJ flying after having swapped the carb.
Runs great, makes lots of power... but...
The manifold pressure goes UP at full power but never seems to drop down
below ambient when the throttle is pulled back. Drops to maybe 700 at 1,000
RPM, a little lower in the back seat, so its not the gauge.
I didnt mess with the manifold pressure line. Seems to run quite smoothly
from idle to full power with good control, no popping. If it was sucking air
I would think it would run super lean and miss.
Ideas? The carb was new from Doug and I de-preserved it properly (I think,
hope).
Jon

Ha! I messed with one of my intake drain sumps as well as one of the intake tubes
when swapping the carb. That may be it!

With the M 14 P engine we have seen many engines where people have installed manifold
oil drain systems, but use the original very thin drain plug which is clearly
not designed to be drilled and tapped to put a fitting into it, and after
a while they will tend to crack! The solution is a much thicker plug which
is designed to be drilled and tapped, and is a long-term solution. We, and quite
likely others, make them.
