(sorry for the reposts -- my last post had some
links that are not allowed, so this version should
display on both classic and modern forums).
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. Is the black smoke on rev normal when its cold?
2. is a little lighter colored smoke on rev normal
when warm?
3. 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
