Brian,
Well said. Geeze this is going to be hard. After I try all the things you
guys are suggesting I have to go back through all the e-mails to see who
said what first! At the very least Brian you will get a bloody beer bottle
opener as a consolation prize!! Thanks again, Bob

Jeez, you guys go to extremes just to get some beer! Are loopframe
guys so poor that they can't afford $5 for a six-pack?
Anyways, I don't think Bob's problem is electrical. If the coil is
bad, then the left cylinder wouldn't fire along with the right, since
they both use the same coil. I recently had a problem with my T-3 (which
uses 2 coils), where only the left cylinder would fire. I swapped the
wiring on the coils, and then only the right would fire. I thought I had
a bad coil, but cleaned all the connections, and everything ran fine.
The +12V wire was connected to one coil, and then another wire ran from
this terminal on the first coil to the +12V terminal on the second coil,
and there was a poor connection in here, so the second coil never got
power.
I also don't think the distributor cap is bad for the same reason. If
the distributor cap had a short to ground, it would not affect only the
right cylinder.
I have to go with the choke or leaning carb theories. Can I get some
beer if I agree with the correct answer?

Yes, ignition has two circuits. The primary is 12 volt and includes the

ignition switch, battery, voltage, condensor, points, etc. Once
energized by
the primary system, the coil INDUCES a secondary voltage of maybe 25,000

volts. The big, fat wires are a secondary circuit which is induced by
the
primary circuit. When the points open, the primary circuit stops. At
that
instant, the secondary circuit collapses with a big whack of voltage
through
the secondary wire set to the spark plugs. There is a little more
engineering in there, but that's the basic. AND, when secondary wires
get
aged at all, they bleed off invisible amounts of their voltage all over
the
place.
