I had my carb apart to day cleaning it and I forgot to tighten the main jet. I run it down the road and all was fine untill my main jet came unscrewed. I limped it back home pull the carb off and found the main jet unscrewed. Of course it was getting to much gas and now it won't run right. Acts like it missing and poping back threw the exhaust could I have fouled a plug?

 

Thats what it sounds like to me, I would stick another one in it, and give it a try.

 

I think I'll I try my old champions in the morning and if that works I'll order me some more NGK'S.

 

ya know the older we get the memory some times fades a little.

 

You can say that again.

 

sportsman70003, when ya change oil in the trans. book says 1 5/8" below the fill.plug.
how do ya gauge that?

 

If you had some way of measuring 13.5 ounces or 400ml that should get you to 1 5/8".

 

Someone had a good reply to that question before but i can't remember.
I think he used a feeler gage, bent a wire hanger or something.
