#3 & #4 run HOT!!!

[Gurrola_J <Gurrola_J@BLS.GOV>]

A funny thing I noticed yesterday when I was tuning my recetly rebuilt
carbs was that the drivers side of the engine was running real HOT while
the right side was cool.  I mean a BIG difference.  I touched the
manifold on the right carb and it was cool to the touch even thought the
engine was at operating temp.  WHile the left side manifold (and the the
whole left side) was very hot, so hot that it started to smoke.  I shut
it off and let cool.  waited an hour or so.  Started her again and about
10 minutes later it did the same thing.  It was so hot, I could not even
keep my arm in the left side to turn the idle and volume control screws
for more than a few seconds at a time.  I have never experinece this
with any other aircooled engine.

I the ignition system is all new running 009, new cap, rotor, wires,
plugs, points, etc.  I checked the gap on all plugs, points and also the
valve lash.   There is minor exhaust leak where the muffler mates to the
header.   It hasn't been driven on the road hardly cuz I'm in the
process of restoring it back to a the daily driver it was.  One other
thing I noticed that it hadn't doen before was white smoke now appears
from the tail pipe.  

I'm planning to do a compression check.  I'm guessing that it might need
rings or some sort of top end type of problem.   ANy other guesses?  Why
would one side run so cool and the other so hot?  Has anyone else
expreince these sort of problems?
