I'm having an engine problem - maybe someone with knowledge could help with a diagnosis ??
Engine is 1725 with twin zeniths. It was running strong then began to stumble, stutter, loose power, and die. If I pump the gas during the death throe sometimes it will backfire.
This occurs after first drive of the day for 10 or 20 miles. After the engine cools down over night it will become good for another 10 or 20 miles, then the same problem.
Broke down beside the road, after 5 or 10 minutes the engine will fire up and run for about 1 or 2 miles, then same problem.
Things I've done:
--Replaced coil with new coil.
--replaced points.
--replaced dist. cap
--replaced plug wires
--replaced condensor
I don't know a lot about carbs, but finally noticed that, during the predictable breakdown, the back carb appeared starved for fuel.
My rebuilt zeniths have been so troublesome that a pair of running zeniths sitting on their own manifold, linkage and all, was installed.
Same problem occurs only today, instead of 10 to 20 miles on the first drive, only got as far as 2 or 3 miles, then same problem.
I now suspect the fuel pump, which is NOS with a couple thousand miles on it by now but does that make sense for a mechanical AC factory-style pump.
If not the pump maybe the distributor is about shot somehow ??
When cold, sitting in the driveway idleing, all seems well. Cranks fine, idles fine but on the road it is certain to fail...
Thank you in advance...
