Problem started with an oil leak at the governor rod. Removed clamp holding the governor rod to inspect seal. When installing the clamp, I rotated the governor rod clockwise to end of travel (about 15 degrees) and clamped the rod. Somehow, I totally wrecked the governor. Pulled engine, accessed oil pan, metal fragments from governor gear all over. Rebuilt governor, put engine back on Scag, set new governor rod clockwise per U-tube video. Engine pops and sputters but will not run. Went to Chat and was told the governor rod should have been rotated counter-clockwise before being clamped into place. I've done this but hesitate to try running the engine due to the damage I experienced after what seemed like a simple adjustment

Move the throttle shaft in the carb from idle position to full throttle. Observe which direction the governor shaft coming out of the engine rotates. Loosen the clamp on the governor arm and while holding the throttle at full throttle rotate the shaft in the same direction it moved when going from idle to full throttle and then tighten the clamp.

So if shaft turns counterclockwise when going from idle to full then turn counterclockwise and while holding tighten the clamp. Or if turns clockwise then turn shaft clockwise.

Had the exact same thing happen to me about a week ago. It DOES turn all the way clockwise and while holding the throttle open where the cable connects to the engine, tighten the screw. I suggest you check over the springs and everything else in the governor linkage so that doesn't happen again.
