Hi guys I was hoping I could get some ideas on what to do next to try and find my problem. I have a small skip/sputter that begins at above 1300 rpm. I have a 67 L-79 with 3500 miles on it and a Comp Cam modern grind L-79 cam. This is what I have done so far
Changed plugs
Changed distributor cap
Changed coil
Taken carb apart and cleaned it
The plug wires are new and looked at them during then evening looking for sparks found everything to appear normal
The ignition has a Mallory breaker less system
The miss is similar to when a plug is fouling but really is only apparent over 1300 rpm. A few nights ago it even seemed to go away but came back. I did not know if maybe the ethanol in the fuel has start to eat my fuel pump?
I would appreciate any suggestions
Thanks,
Lawrence
