"was running lousy at low rpm, like it was missing every other stroke. Sometimes one cylinder would quit completely for several seconds, fire a few times and then come back on line. (Don’t know which cylinder.) My mechanic changed the carbs out with 1990’s and also replaced the fuel pump, which he said was leaking. As a result my fuel economy went up and the motor smoothed out very nicely…for about ten hours. Then it started doing the same thing and got worse as time went on. End result, I’m back where I started.
I have changed the plugs, no help. I’ve added octaine booster in hopes of overcoming the ethanol possibility, no change.
One more new indication. If I go to full throttle my tach dies. As I throttle back it comes back on line. That is getting worse also as it is now showing false readings.
My question: Do I have a fuel problem or an electrical problem or both? How do I separate the two to determine?"
