Guys I searched the forum looking for this info, but did not find exactly what I was looking for.....

 

I did a compression check on the S-12D and it was reading about 95 lbs.......then I did a compression check on my TRA-10D and it was reading only 65 lbs......

 

So does this mean the 10 is needing some attention?? It cranks up fine......

 

Both are running really rich.....so I can to do some reading on how to fix this.....

 

Any help will be appreciated!

The TRA-10D came equipped with automatic compression release so any reading you will get will not be fully accurate.

A perfect reading should be around 110-120 lbs on these.

65 Is pretty low but if its running good with no smoke and has enough power to do what you want to do there's nothing wrong with leaving it go another few years.

Add some Marvel Mystery Oil to your gas from now on. Adjust the carb properly.  Check the compression in a couple of months.
