For those who remember,
Last year Don posted pics of this tractor with a homemade blade pivoted on truck spindles and a winch to move the blade up and down mounted to the radiator. The engine was stuck (pistons and valves), water jacket cracked, the exuast manifold broken and the heatbox fractured into pieces.
A year later and a lot of work the kids have have it to running again. The picture is it's first trip out of the shop. During this project the bearing clearances were set, cylinders honed, new rings installed, valve job, carb and fuel lines cleaned, mag cleaned and timing set. The best part is the kids did all of the work (except the headwork) and all I had to do was repair the heatbox and watch the rest. The tractor now starts easily with the handcrank and idles well.
Now for the issue:
The engine seems to run a little warm (160-180) and be short on power. I figure either running lean, a governor issue or the timing is retarded. The timing was set with the (mag) mark on the pulley. I understand that the timing is retarded 35deg while cranking. If I wanted to use a timing light to check the timing, how many degrees should it be running and at what rpm? How is the governor set?
The throttle does control engine rpm, but it just does not seem to power up when going up even the slightest incline.
