Okay, after working on flooding issue (still have that problem) I reinstalled carb engine started but wants to run away. I never messed with any linkages ( had carb on and off at least ten times, each time it would start and not run away) but this time it runs wide open cant throttle it down, when i try to manually move linkages by hand they dont budge????? ?/ engine will not slow, what happened????? how do i fix?????

Sounds like something is stuck or the linkage is binding or has been tweaked way out of adjustment.

Try this first...

With the engine "OFF", set the throttle a little above idle and try moving the linkage between the governor and the carb. It should be free to move, with little resistance, through the complete range of motion of the throttle butterfly shaft.

i took gov off, i found the bumper spring on gov housing ( not the spring with bumper in gov shaft)it was broke in the bottom, this spring rests in the bolt you can adjust on the bottom of gov housing, will this make the gov run away (motor), what exactly does this piece do?
