Original owner of a Harry Ferguson TO-30AB, bought in 1951; Serial # 118384; Engine Z129 3J9571
Need help troubleshooting this problem:
Ran fine in the past and this summer until recently; mowing fields with bush hog, hauling things in trailer, etc
Now, it starts all right, runs 5-20 minutes, then starts skipping, surges, and quits
Choke can keep it marginally running briefly; can restart after 1-2 hours
When running, it responds well to governor control
Have used non-ethanol gas since it became available here a few years ago
Recent maintenance to track this down -
Cleaned outside of radiator; fuel sediment bowl; air screen
Checked generator, battery
Changed spark plugs
The exhaust is not clogged; the manifold seems quite hot
Other parts replaced in past few years -
Water pump, 2017; also filtered the antifreeze then
Starting motor, 2016
Fan belt, 2017
Condensor, nor sure when
Thanks in advance!
