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?

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. Patrick Hayes Fremont CA EV, EV, SPII, V-65-C, Monza, SuperAlce MGNOC L-403 |
