Champion H14-Y or Autolight 437. Replace that plug wire. Maybe a weak spark, --->fouling.

: have a 4 cylinder gas ford 801. #4 cylinder keeps fouling the plug. did a compression test and it was equal to other cylinders. tried to find a hotter plug than the champion H12, but was unable to locate one. other than using a hotter plug what other suggestions are there for keeping that cylinders spark plug from fouling? other than that cylinder plug fouling tractor runs beautifully. any ideas?
