I don't know of any timing marks on my Farmall bn gas tractor with horizontal distributor. Nor do I know what the timing should be set to. I do have a Sun Tune up kit with timing light and tach/dwell meter that I've used on my classic cars that have timing tabs.
Help appreciated.
I recently changed out the distributor amid chasing an intermittent spark gremlin. It is not impossible that it may be a tooth off. I tried really hard to install the new one in the exact orientation of the old one. Since I did it, the idle hasn't been as smooth as it used to be, and there is a a stumble when applying the throttle that didn't used to be there or as least was not prominent.
