1962 would be 24:1. Older models vary. I could post a chart, but it would start an arguement. Besides, there is more than one chart.

Generally speaking, for motors of the 1950's motors 10hp and up are 24:1 and below that are 16:1. Most of the 16:1 were changed to 24:1. There are exceptions.

1964-up are pretty much standardized at 50:1.

The 63 3hp was the only motor in that year with the friction based crank and rod assembly. It wouldn't hurt it to run at 16:1 either. All other motors had needle bearings. Excellent little motors though.

1/3 pint per gallon works out to 24:1, j67man, just as said above in the OLD thread that you have hijacked. That is not good forum manners. Please start your own thread.

Thanks for your cooperation.
