Have you tried adjusting the main jet needle? It's the one that points straight down out of the bottom of the float bowl nut.

Jep i did, when i turn that open (now it is about 1 and 1/2 turn open) from 2 it starts shooting flames true the exhaust when rev up and back to idle.
spark plug have the right color so i think mixture is good.

when i hold the arm i can feel it pushing.when u put a small screwdriver inbitween, it runs normal... I'm starthing to think the governor have a problem.

no wthe engine have not enough revs/power to mow.
riding is just possible but it's like riding a camel. (lol)

Governor spring needs replaced is a common cause of that.

New governor spring did the job.
