Hey Mad Dog, all ignition components are new. Spark plugs,
coils and wires, new breaker plate with points and condensers, everything. But
here is what I found: after pulling the carbs off for the millionth time, I
finally noticed the cast tube on the carb body that the main jet screws into was
cracked. I filed all around the housing and put JB Weld all the way up. Seems to
run good now but not sure how the JB Weld will hold up. I got the stuff that
said "for gas tank repair". #4 carb was starting to crack too so I did that one
too. I would feel a lot better if I could buy a decent set of carbs to rebuild
and put those on without spending a ton of cash. You know anybody with some?
Thanks for the reply. Paul
Have you taken the ends off the plug wires ( they unscrew ) check
them if the wires are burned back into the insulation cut the insulation back to
good wire and reinstall caps. To find your problem cylinder start motor and
spray water on each exhaust pipe. The ones that don't boil the water instantly
are suspect no fuel or no spark. We use ultrasonic cleaning to do our carbs this
is the only way to get them clean.
