HELP! 372xp OE bogs under load

[sunnyside]

Hi
I've a 372xp OE MMWS (Robin Wood) that bogs down under load. Idles fine, runs awesome at WOT. 3/4 throttle will run as long as it has gas.

I have; changed carb, pulled cap off fuel tank and held at angle to make cut, checked lines, done vac/pres test, no spark screen on exhaust. good air cleaner. changed fuel filter. Not sure what to check next.
I'm open for all options

Welcome to the forum!! I would guess it isn't getting enough fuel, not sure if this video will help or not:

Yes the high speed adjustment screw is likely the culprit and last thing to do before replacing the ignition coil/module. I think you’re close to the end of your challenge. Let us know how it ends.

Replaced the coil, runs like a champ
