Quote: A burnt valve wouldn't cause popping through the carb. You'd have a dead cylinder and/or popping out the exhaust with a burnt valve. Exhaust valves are the ones that get burnt. I've NEVER seen a burnt intake valve.
I have. Made a rhythmic popping noise out of the carb. Didn't stop me from driving home from the shore though.
All this talk about spark plugs and carbs... I would do a compression test and a leak down test right away.
