First the throttle speed control is over rotated. the linkage between the governor arm and carb is backwards, and the throttle shaft needs to be flipped back up over the stud, so it rotated clockwise.

Rivets, the small spring is the auxillary governor spring.

Don't see a remote control hookup in your picture. Do you have a speed control on the handle?

no i don't.

but good news is, i fixed it up a bit, but this time the engine is running way too fast. im afraid it will explode. its late here, so i will post pictures tomorrow. ty.

Bending the tab on the right (oblong hole) in should slow the engine down. Engine speed should be 3200 RPM's. Those springs are governor control springs and because you don't know what they do, be very careful when adjusting them. Might be time to get a mechanic.

Yes it can, or the blade may break if it is old. Had this happen on a lawn boy deflector just this summer. Lucky no one was hurt.
