I have 1957 861 with 6 volt system. It idles rough below 600-700 rpm. All other rpm's seem fine. I've tried adjusting carb with no luck. I put in new points and plugs (autolite 437). I want to check the timing but I am not sure if a regular automotive timing light will work on a 6 volt system. Can a guy manually adjust the timing by moving dist and listening to the engine.
Thanks for any help.

Crank the engine around by hand and mark all three timing marks, 4, 13, and 24 deg. That is the only way you will be able to see anything. ray

I just got the accumulated crud off the timing marks on my 861 & the next session will be to set the timing. Why mark the 4, 13, & 24 hashes? The 4 degree is at idle, right? What speeds are the others for? I didn't see anything in the book about this. (Maybe someone could become a writer a la Haynes or Chilton for tractors... or tractors for dummies. I'd buy!)

Actually, I just checked the Ford shop manual, page 95, and it shows for the 8X1 series a little different:
1. idle 5 deg

2.1200 rpm 14 1/2--16 1/2 deg. Yeah, right, I am sure you are going to get this half degree thing right on.

3.2200 rpm -26-28 deg

Just make sure you are getting advance.

Sometimes timing by ear is best. It is difficult to see the timing marks on that unit, but a timing light will work. BTW Ford did not make the *01 series in '57. You either have an 860 or a later tractor.
