Best way to check for air leaks
What's the best way to check for air leaks? My pro 1200 all of a suden will rev to 3700 rpms as soon as I start it. I pulled the carbs and checked over everything and replaced the intake and carb gaskets. I must still be getting an air leak from somewhere.

My ski idles at over 3G when out of the water, being in the water creates resistance on the motor, therefore bringing the idol down.
I am not saying you shouldn't check for leaks, just saying that it's normal to have a high idol when on the hose.

Put the ski in the water first. Then start it and see what the rpm's are. then spray WD-40 at the case seams and see if the rpm's change.

Has anyone ever tried to do a leakdown test with the pipe on? It seems like the coupler can be taken off and the pipe can be blocked with a raquetball,then you would only need to remove the carbs.
