Gonna redo the test. Want to make sure that I was getting correct readings.

Do you just use an air nozzle from the compressor with maybe a rubber stopper with a hole in it? Wonder how much air presser?

The leak down tests I have been involved in used 80 psi.  And 80 is enough to put you in the hospital. 

All you could ever want to know about leak down compression tests...

Re-did compression test today with my brother helping. Found a loose fitting on the comp gauge. Test now shows 140 on one side and 145 on the other. These numbers were achieved during the third pull thru of the prop. I think I’m gonna call that good.

Yes I did. Wasn’t overly enthralled with it. The Mosler case does not have the bumps and things to attach to like the vw case does. After many attempts to get the carbs to stop dumping gas, I’ve given up for the time being . In the interest of getting back in the air sooner,( Maine summers are short),I’ve decided to use the single zenith Carburetor mounted underneath. This engine was rated at the factory at 40 hp with that set up. I know this means carb heat. Already in the process of making a 2 into 1 exhaust system that I can grab some heat off of with a muff. At least the new direction has renewed my enthusiasm, very important to be enjoying this whole project.
