I mess around on the weekends with a restored M&W P-400 dyno.

We time motors with a digital timing light with a tach built in.

When you establish a final rpm that your happy with we time it.

Clip the pick up to cylinder #1 wire and spin the motor up to full throttle. At this point watching the tach in the timing light turn the dist. tell you get max rpm.

This works great , but we get even better results doing the same thing under full load of the dyno.

Under load we have seen 4 to 8 hp gain and this is on stock motors.

We have messed around with light weight springs on the advance weights to bring in full advance real fast.

I always woundered how much actual advance we would really get with a stock dist in a Super M with those bed springs they use on the weights.

The springs are so heavy and the rpm is only 1800 so do they really open.

Keep it simple these old tractors are sloppy.


A pulling tractor is another story all together MSD/crank triggers/ high out put coils/ timing retards etc etc etc....

Today's Featured Article - Show Coverage: Journey to Ankeny - by Cindy Ladage. We left Illinois on the first day of July and headed north and west for Ankeny, Iowa. Minus two kids, we traveled light with only the youngest in tow. As long as a pool was at the end of our destination she was easy to please unlike the other two who have a multitude of requirements to travel with mom and dad. Amana Colonies served as a respite where we ate a family style lunch that sustained us with more food than could reasonably fit into our ample physiques. The show at Ankeny ... [Read Article]
