    since the piston resides at tdc and bdc for several degrees of crank rotation, you can be off several degrees with that method

    and if you happen to be doing it on the overlap stroke, you will not only have a mess in your exhaust but on a flathead can creat a hydraulic lock in one of the other cylinders

    I checked it several times and it always stopped on the same mark. That just happened to be where the pointer was set with a dial indicator. I do not understand how you can create a hydraulic lock with air? I am using the air to move the oil in the vial. If you have a better method, please advise.
