Replaced float, set to proper settings. Tractor runs good. Still dialing in carb 1/8 of a turn at a time, started at 2 turns out. Cut grass for 30 minutes, then she just shut off. opened hood, coil + wire broke off. replaced end and rebolted to coil. Had hard time starting since it was hot. Maybe this is a timing issue??? Also when going into higher grass, tractor wants to bogg down. Is the governor supposed to pick up the slack and keep the carb running at the same rpm? Please need help with this. going to check timing tonight.
