John, i am going to give the ngk plugs a try. i ordered a couple 5812 plugs from Oreillys.

Normally on a car the plug gap is around .035 to .060 inch so at .020 i thought maybee the gas mixture was not reaching the spark every time. The modification i did helped the junk stock dl plug so now that i know where the problem is. I am looking forward to seeing how the ngk plugs perform.

Thanks for the suggestions everybody.

Mike
