Re: Misfire mystery
Received the Renners jet kit and rebuilt a third carburetor. No change in the misfire.
The carburetor is more sensitive to adjustment now with the Renner's jets.
Tried closing the spark plug gap to .030, thinking maybe a weak coil or ignition system having a hard time jumping the gap. No real change....
Its just so random, I cant say its a mechanical issues such as cam lobe etc.
My coil is an Oreilly Master Pro 6volt.
I did check my air gap at the distributor cap contacts and rotor. As the rotor first approaches I have just under .019, as the "blade" of the rotor passes to the end, I am over .025. Pretty consistent on all four.
Cap is new and I tested for carbon tracks or "bleed over" from one contact to another.
