Trying to pictured this procedure with a lever style throttle.

Why do you feel the need to question my comments and knowledge? I made a statement for the OP. I’m going to remain polite and just let you be. Good night.

It’s obvious you haven’t seen everything.

Blow downs. All the reason I carry a small chainsaw. Hate to get up trail and not get out due to a felled tree. Glad you were ok. 👍

I beg to differ. As a mechanic for 40+ years, I’ve seen plenty of burnt intake valves behave the way the OP describes the symptoms. A flat exhaust cam lobe will also cause a spit back through the carb. A compression check is needed.

Many good answers above. ‘Another might be a burnt intake valve causing a backfire into carb off idle or under load. Take a compression check. Good luck with your findings.
