Whats spark plug gap?
ok before i changed my plugs...on mornings it was cold...i start up and i rev and its kind of like a delayed rev where i hit the gas and it takes a second for the engine to rev...then it backfired.....my friend works at autozone he said its fouling of the plugs....i go buy 8 new ones....he said to gap them at 35 thousandths....i do so and its backfiring worse...i look at the old plugs and they are at 40 thousandths...i put the new ones to 40 thousnadths....and it seems to be fine?? since its a further gap are those plugs going to mess up in a couple months?
thanks, tim |

Re: Whats spark plug gap?
I would check your timing first. And if your truck still has points make sure they are gapped properly and not burnt or pitted. It is unlikely that the spark plugs are the culprit.

Re: Whats spark plug gap?
The delay in the revving might be the cold too.....carbs dont like cold.
