After some recent major changes to my engine, I've started fouling plugs after about 1-2 hours of use. Seems to happen under load and idle. The symptoms are engine starts misfiring, as if she is starved for fuel, and then she ultimately stall.
This was not happening before the changes. I've been going back and reading all the posts about fouled plugs trying to eliminate all the possibilities, but I thought I'd go ahead and try to get some feedback from you guys... Here's what I've done recently, not sure which items may have caused the plug fouling:
1. Removed and replaced head and head gaskets w/ new moyer ones
2. Fully took apart carb and cleaned it
3. New coil (I bought this from napa and didn't check the ohm rating with a meter yet... is this a potential culprit?)
4. New plugs (same J8C that was originally in there)
After these changes I started getting fouled plugs. Since then I've done the following to try and fix the issue:
1. Took apart and cleaned carb again
2. Set timing by rotating distributor at cruising speed
3. Tried hotter RJ12C plugs
4. Reset idle mixture screw and set idle RPM (I could not get it to idle right at 800 though... more like 950rpm if my gauge is right)
5. Adjusted choke linkage to make sure it was set properly
Throwing in a new set of plugs instantly fixes the issue, so I have to believe that that's the only problem.
