    2 Stroke engine pressure test

    Ever have a motor show a leak-down on the pressure test, but you cant find it? I have a 1200pv motor that was losing 10psi in about 15minutes, and I just couldnt find the leak. Waisted a whole bottle of soapy water on the damn thing!

    Did the exact same thing on Kale's motor a couple years ago. Just blow the motor up on test, stuck it in the plastic shipping container filled with water and the leak showed its ugly face right away! Yes, this does work very good. Good post WFO

    I perform a pressure test to verify the water jackets are sealed. I ran the 1/4" line from the front of the exhaust manifold to my gauge set-up, plugged the main water inlet and looped the head outlets together, filled to 30 PSI and let it sit.
