Well I took the engine apart as a leak down test showed the valves as being good. The exhaust valve cam lobe is pretty much worn down to nothing. I ordered a new cam and the gaskets needed to do the repair. No idea why it was opening a lot more on occasion but I suppose it was just me seeing...

This is the video of the valves, I'm gonna take the engine apart tonight and see what the cam looks like. https://youtube.com/shorts/OkH5l-maT_Y?feature=share

Yeah I can still see it do that, but it can take several revolutions sometimes before it will open more.

So.... I feel like a dope but I noticed something when I put the head back on and checked the rocker arms again. Sometimes I will get the full lift out of the exhaust valve, and other times, (most of the time now) it only opens a very little bit. I can't say I've seen that before but I'm...

Gotcha, so in the mean time I did yank the head off it and pull the valves out. As far as i can tell the guides are tight and the valves are sealing as they should. The seats are tight and clean and the valve faces look good. I might lap them anyway while its apart. The flywheel key is good. I...

Could a bad igntion coil cause this? I seem to be getting a pretty weak spark from it, sometimes sporadically it seems. It might just be I cant get a good ground on the plug too. Personally I think that's too easy. It sounds like a loud exhaust coming right through the carb when the throttle is...

I was wonderings about it being an ignition issue as well. However it does seem like a valve issue from the way it is popping back like that. I will probably end up pulling the head to see what's going on. For what it's worth too I probably remove the rope start assembly and hub so I can see if...

This is a link to it running, the throttle is close to wide open and the loud poping sound is coming from the carburetor intake. https://youtube.com/shorts/m3cqv_rbjWU?feature=share

I have a 10hp OHV briggs engine on a yard blower. It starts up fine and idles but it pops like crazy through the intake as soon as it goes up in rpm. If I take the air filter out it sounds like a 2 stroke engine without a muffler. The engine sounds like its struggling and it never really gains...

Thanks for the help everyone, I figured I'd post the fix and unfortunately I made a stupid mistake and put the magnets on wrong. I ended up sourcing a used flywheel and that fixed the issue. But better to make sure of the problem than to throw parts at it. Charges great now though hah.. :rolleyes:
