Hi all,
I have a '49 8N front-mount distributor. It has been converted to 12-volt with the appropriate resistor. It is not running good. Here are the symptoms.
First, it starts fine and runs fine after starting while not moving. However, when I start brush-hogging, it seems to surge and back off. The longer it runs, this gets better. After warming up after a couple of rounds of the field, it only does this when staring up a small incline or in a turn.
After the above problem goes away, the engine then starts running rough. This is after about 20-30 minutes. Then the longer it runs the rougher the engine runs. This reminds of the a bad coil, but the coil is not hot to the touch. Also, it begins to backfire a little bit. Today while mowing, it gave a big backfire and quit. I started it back immediately and finished cutting, but the tractor continue to run rougher and rougher. It only takes about an hour to mow the small field.
Does anyone have suggestions as to what could be wrong. Perhaps the two problem are not related. The second one sounds like it may be electrical to me.
Thanks,
Allen
