mm u distributor timing

jr1983 · May 23, 2014

I replaced the distributor driver gear on my 1950 u. I have it timed pretty well but would like it to be exact. Are there any timing marks to facilitate a timing light or do u time it by ear?

Should be timing marks on edge of the flywheel

Access hole is on left side.

book shows timing with engine running at 3 1/2 to 3 3/4" before TDC.

and also if anyone took the flywheel out and put it back in the right way the marks might not be right.

jr1983,
Open the clutch adjustment hole. The timing mark pointer is cast into the case. There are two spots marked on the flywheel. The first is marked "DC 1-4" and the other is 2-3 at 180 degrees opposite.

Run the tractor at least 1250 RPM when checking timing. Make sure the points are set at 0.018" to 0.020" clearance. For low compression fuel models; set the timing at 27 degrees or 3.75" BTDC. For high compression fuel engines; set the timing 25 degrees or 3.5" BTDC.

Happy wrenching.
