I bought this thing full of gas in the crankcase. Pulled the tank cleaned and replaced all hoses, filter with a shut off valve. Would only run with choke on and best with full choke with an occasional fart and would hunt on slow and die. Put on a new aftermarket carb. Pulled the plug and cleaned it and checked compression. It was at 90 psi in about 4 revs. Pulled the head and found the intake valve worn from the spring keeper but not broken. Put in a new valve, keeper and seal. Also found the intake push rod was worn, probably from the slop and bought a new one. Plastic intake seems OK but I could not get the plug out of the bottom to connect a gauge and didn't want to break it. I have not checked the govenor arm adjustment yet. The occasinal fart from the intake side and acting like it has a vacuum leak has me stumped. Yet I can go out pull the choke and it will fire right up, but take the choke off and it will hunt and die.

Anyone had a similar issue?

The intake to head mounting gaskets or O-rings are possibly leaking. What appear to be a plug on the bottom of the intake is not.

According to Parts Tree these have a camshaft update number, so it may have a very worn camshaft lobe.

I had an old Yard Machines mower I recently sold with a 13.5 hp Briggs engine doing the same thing. Tried OEM carburetor three different times after cleaning and messing with intake gaskets, replaced with another old carburetor I had after cleaning, same thing, only run right on choke. Bought a cheap Chinese carburetor and installed, and bam, she was great. Maybe try another cheap carburetor after triple checking gaskets.

I have another one coming. You can't beat Temu for giving you a refund when the thing doesn't work so you can order another for $10. When running on full choke the speed is increased so I am not sure what it would do if I tried to idle it down.

Anyone that sends back $10 parts that don’t work for a refund needs to seriously reevaluate life.
