After swimming about 45 minutes Amphi's 4-banger suddenly became a 2-
banger. No overheating of the coolent. We limped to the ramp (w/
extreme "putting" all of the way, but lacked power to pull out. About
the the time a friend came w/ a line to haul us out, Amphi started and
ran fine. We pulled out and drove home. The smell of unburnt fuel and
a backfire leads me to believe it is electrical, not fuel related.
Subsequently, an hour at fast idle has not duplicated the problem.
I am replacing those items dedicated to individual cylinders (cap,
rotor, plug wires and plugs), but that still leaves the coil and
Pertronix module. I would think failure in these areas would not cause
the 2-cylinder symptom, . . . . but . . .?
The positive-ground, 41-year old coil gets too hot to touch for any
length of time, but I understand that is normal. Any ideas?
Thanks,
