What nut? Take the fuel shut off valve out?
View attachment 53699

You'll need what looks like a 1/2" wrench, and screw that out using the two flats just under the carb bowl on the upper part of the valve.

Yeah, the solenoid acts as the nut. Just take a 1/2 inch wrench an loosen it slightly, the just unscrew it a bit. Try and catch what dribbles out to look at it, that water can be a pain to fully get out of the system, but it does sink and sit in the bottom of things. Which is why it acts up when turning sharply, bouncing, etc., then a tiny bit of water sloshes up into the engine.

You may have to get a cheapo wrench and grind it a little thinner to get on the flat surfaces of the solenoid.

just unplug the wires before turning the solenoid.

Will do tomorrow, Thanks.

The only thing I wonder is why does it do it every time I throttle all the way up also? But doesnt stop until I throttle back down?

I cant run at full throttle.

Tried it and it still does it. Noticed small crack in upper gas tank though during the process and ordered a new one. But did what you said and it still pops like in the video at higher rpm and going up hill with blades engaged.

New air filter?

New air filter?

Yes with new carb.
