Briggs Intex 18HP constant backfire

You sound like you have a bad cam lobe, now that we have some info. I guess we can trust this info. You will need to pull the
engine and go into it. It is not too big of a deal....

But either way, you will need to buy some feeler gauges, to confirm things.

Really, this stuff is not all that complicated, it is just a matter of folks giving accurate details usually.

What do you mean, "Anyone else"????

You just laid it out plain by finally responding to a question or two.

I seem to have offended you, I'm not sure how, but I apologize and I appreciate your help. FWIW, what I actually said was " If anyone has any other ideas, please let me know. thanks. " Again, sorry if I said something wrong, but I'm not sure how else to say what I said.

Well if your valves are adjusted properly, when you rotate the engine, the valves should open equally the same distance, if one barely moves, that indicates a wiped out cam lobe.

Here is a pic of a cam with a wiped out lobe, and is why the compression reading doesn't really help much.
