Does anyone know what the proper gap is for points  on a  ford 300 6 cyl engine?Burning propane if that makes a diference.

Thanks, Burlkraft.  Been meaning to get an electronic deal to put in there.

I would suggest .020, that seems a good starting point for most 4 cycle engines. .015 will get most 2 strokes started. I think I can still remember how to do it. ;D

In a pinch you can use a matchbook cover. It gives about .015" as a result. One thing we miss when setting points is that it directly effects the timing of the engine. A wider gap advances the timing I think. If you have a dwell meter that is the best. Set the points to 15 and then start it and set again to the proper dwell. Points also close as they wear the little rubber. Setting them a little bit wide gives longer lasting results.

But if you have a timing light use it last to reset the timing.  Joe

I'd set 15 or 20 thou, 30 is more a plug gap.

For a 1973 300 I-6

plug = brf-42b
gap=.035

dwell = 33-39
point gap = .027

timing = 10 degrees btdc

idle = 600 manual, 550 automatic

I was gonna vote .015 - .016.  On older engines especially if they're running constant speed a few thousandths probably won't make much difference.

If you're serious about a solid state unit, Google up " PERTRONIX".  We found a distrubutor for an old Clark fork lift from them.  Probably $250 range.

cant remember the year-----but go get the electronic setup in a later ford pickup---distributor,wiring,and control box-------------only two wires on the silver electronic module--red and white--and the red hooks to key hot------and can get parts anywhere----- ;D ;D
