    How to pressure test 701 T crankcase with motor in ski?

    Hi all,

    I have a surging problem and after a lot of research etc. it has been stated I might have an air leak in the crankcase. Is there an easy way to check the crankcase pressure on a 701 T while motor is still in ski? Motor is a 95 and all original, or at least that is what I have been told. Anyway, front cylinder's pressure was 149, rear cylinder is 149 dropping to 120 before holding.

    Thanks is advance to all for your assistance.....

    BTW, I tried searching but didn't find a thread detailing how to check Crankcase PSI, I just found that ideally you want it to hold 8 psi.
