steve s - Well you will be happy because I checked for fuel flow!!! It was fine. I also checked the filter in the front of the carburetor. Nothing there either. I'm on another mission trying to get head off but when that is done I will be opening the carburetor up.

After doing a compression check and finding #3 was low I did a leak down test and I could hear air coming from #4 but when I reversed the process the air coming from #3 was not as great as what came from #4. My conclusion is the head gasket is blown so I am trying to remove the head. I don't think it has anything to do with the backfiring.

BUT my question is if the head gasket is blown why did #4 show 60lb. while #3 had only 48lb.
