Help with carburetor please

[WAYNEWCU]

Backfiring at engine shutdown can be caused by not bringing the engine to a low idle before turning the engine off.

Often when you replace dirty old fuel with clean fuel, it dissolves gunk from inside the fuel tank and sends it along to the carburetor, which might explain why your machine suddenly stopped working.

Good for you! Not every manufacturer uses that term. When I grew up we often called them flat heads, but when we got corrected by the guys who had a different term we started referting to them as under head valves, for that is what they are. I've also heard them referred to as "valves in block".

I have heard all 3 of the terms. Supposedly "flathead" came from the ford V8 because of the flat heads vs the looks of other automotive engines. All the briggs literature i have seen calls them L head. If you want to work on a fun engine work on an F head engine.

Whatever, if the valves aren't in the head, it's pretty damn flat. Call it what you will.
