Hi, bought a ford 860 last winter. Have not used it a lot other than some snow plowing, grading, and pulling logs for firewood. When I got it, it was running rich as evidenced by the soot from exhaust:

Some observations since I've had it:
1. when I first got it, it would sputter when I revved up engine
2. cleaning the air cleaner seemed to help with the rev-up some
3. someone told me to spray carb cleaner into the air intake while running, so I did that -- did not notice any huge changes after that.
4. at some point, I was doing some heavy grading on a hot day, and the tractor started to backfire, and would not run unless I had the choke out. That has not happened since, but I've probably not run it that hard since. I've also installed a temp gauge since then.
5. perhaps in early summer, its started running rougher
6. checked the spark plugs -- the front one (by the way, is that #1??), and it was oily. The rest were somewhat black with some carbon buildup, but dry. I cleaned all the plugs with a brass wire brush, and it runs much better now -- very smooth, and a lot more power than before I cleaned the plugs.
7. checked compression the next day -- ran it until it was warmed up good, pulled all the plugs. Compression was around 147 lbs on every cylinder -- the readings were very consistent -- I could not tell any difference between the cylinders. Front plug looked about like the others, but it might have been slightly wetter -- could have been my imagination.
8. when engine is cold, it blows a little black smoke when I rev the engine, but it revs decently. When its warm, and I rev the engine, I notice a very small amount of light colored smoke. Under moderate load (run in higher gear while pressing the brakes), it runs good and I don't notice smoke.
Questions:
1. what is normal operating temp for a ford 860? I installed a ABC081 - Water Temperature Gauge With B and it seems to operate about 1/3 into the green.
2. Is the black smoke on rev normal when its cold?
3. is a little lighter colored smoke on rev normal when warm?
4. does compression of 147lbs sound about right?
As the plugs are getting fouled, it seems like I still have some work to do, so appreciate any suggestions on the next steps. Thus far, I've refrained from messing with the carb adjustments, until I get through the other basics.
Thanks,
Cliff
