I think the # on the old plugs was AC 303. I did check the gap and they were right on .35 and they didn`t look THAT bad to me.I did have some carb/fuel/rich issues when I first put the motor in so either that was the completely wrong plug, or they got fouled. Funny thing is, once it started it ran like a top. Duz run better now tho. Thanks for the input, if nothing else it motivated me to get off my duff and chase the gremlins.
