Frieda the 66 coupe started acting up this morning. Runs nice the first 3 or 4 miles then starts to lose power and won't take the throttle, but revs OK. After another mile or two, she just won't take the load at all. You can kinda limp along but at no real speed. After another miles she will just barely run and has no real ability to rev freely. Stop and let her set 15 to 20 minutes and the cycle repeats but may be a mile or so at first, and progressively less, the further one goes.

I managed to get to work and let her sit for about 5 hours and the same cycle as above, repeats.

I noticed a faint electrical smell in the cab this afternoon, kinda like a hot transformer. I wonder if it's possible I have a 38 year old coil dying?

Fuel flow is excellent and points, plugs, wires and distributor components are recently replaced and/or adjuste, timing is spot on. The coil is NOT hot. Never had a coil go bad before... how do they usually behave whwn failing.

Probably the best bet is put it on a Sun machine to see what the coil output voltage and curve is, eh?

Thoughts?

Thank Mike
