Have Craftsman LT1000 with 18 hp OHV engine. Just installed new carb and adjusted, replaced the armature, wire, and plug, new fuel lines, filter, and fuel, and adjusted the valves. Still it pops at times of high RPM, turning sharply, heavy load, going up steap slope with blades engaged, or when hitting bumps like roots, etc. When it happes it seems to be every stroke and coming from exhaust. Engine #31E777 0443 E1. Any advice or ideas. I have video.

Drain the water out of your carburetor!

Carb is new. New gas and fuel lines too.

Do you have good fuel flow out of the lines?
Did you clean out the gas tank?

 

[Klyonh]

yes and yes. Does that sound like not getting enough fuel?

Turn the choke on and turn the wheel to the right. Try to make it sputter with the choke on.

Loosen the nut on the bottom of the carb, let some fuel dribble out a bit, then try to run it and see if anything changes.

I thought it was automatic choke. How exactly do you manually turn it on. And what does turning wheel to the right have to do with anything? (Dont have much experience with small engine, sorry)

What nut? Take the fuel shut off valve out?
