    Ive got an older 22 hp Kohler. Model #CV22S. When I engage the PTO electric clutch the engine seems bog down like there is no tomorrow. I have done everything I can think of. Plugs, filters, carb rebuilt, muffler, and the old pull one plug wire off at a time(no difference on either cylinder). I have even taken the belts off of the blades so there is no load on the engine when the clutch is engaged. Could this be a bad PTO clutch or maybe both ignition coils are going bad?
    Any help would be greatly appreciated.:confused:

    You might check the engine compression to set if it is up to or near spec.

    I would suggest looking closer at a bearing trying to lock down in the clutch.

    Don't know why but I never thought of that. Looks like ive got something to do tonight. Any idea what the compression should be?
    Thanks again.

    Sure I can. But, A good clutch isn't enough load (with no belt) to shut a engine down even if it had less than 120 lbs.....

    100-140 psi is good

    Checked the compression last night 130 and 135. I think I can rule that out as a problem.
