    Just back the ski into the water, disconnect the valve, aim it away from the carbs, and wait for it to squirt as you watch the tach.

    Yes I know that I am building a custom valve at the shop and want to get the cracking PSI close before I install. On the 785 the cracking PSI is 2.5 at 3200.
