    See my signature links. Look for the 'rope trick' in the PTO cylinder.

    Got it!
    There is no mention of the small set screw in the coupler. Doess it need removing before loosening?

    It is not a set screw, it is a needle style grease fitting. Should not need to remove it.

    When removing the coupler does the pump still need to be removed. Forgive my ignorance but is it necessary to remove the carbs before lifting the engine out. Seems if you could wait until it is on the bench it would be much easier to remove them then

    You need to remove the pump, to pull the driveshaft to be able to get the coupler off.

    I find life is MUCH easier if you pull the carbs before removing the engine. With a stubby 12mm wrench, the carbs are easy to pull.

    Ok: what is the coupler, the fitting on the crank or the bearing like thing clamped half way down the shaft. If the coupler is reffered to as the fitting screwed on the end of the crank, is the driveshaft splined or something so it will slide out of it when removing the pump?

    Advise on the carb is appreciated, I'll remove before pulling engine. Had them off recently anyhow so I know what I'm in for. Really wasn't that bad.
