Eric:
With the valve cover off, watch the travel of the intake vs. the
exhaust valve as you have someone crank the starter (or just watch it
with the engine running). Make sure both valves are going through their
full travel. It is possible for one of the lobes on the cam to go flat
and still have good compression and leak down results.
I had similar problems with my number 2 cylinder until I
overhauled the engine and discovered that the exhaust lobe on number 2
was all but gone.

Subject: No 1 Cylinder Problems
Having difficulties with poor combustion on the no. 1 cylinder on a 76
TR6.
Have replaced plug wires, cap, rotor, reinstalled points (was running
petronix
unit), and still the no 1 plug runs sooty black. Other five plugs are
running
a nice light tan color, so I believe the carbs are adjusted ok.
Compression on
all cylinders is between 128-130. This car is basically a stock setup,
although the air pump has been removed. Anyone have thoughts on next
steps to
correct??
Thanks,
