    Bring your MAG cylinder to top dead center. The CEN and PTO cyliners should be at the exact same height. In reality, you should use a dial indicator to be sure the MAG cylinder is actually at TDC as being a little off (even a couple degrees from TDC) will make the other two cylinders not at the same height.

    well got the mag cylinder at tdc with calipers and the center and pto are only off .200 no wonder it just backfires through the exhaust and wont start ,well that is the work that short block r us did I guess

    You can accurately check the index in the hull by taking off the coupler and putting a small degree wheel on the threaded end of the crank. Then put a pointer on there and use a dial indicator.

    I would double check again with a dial indicator instead of calipers. Like I said, being a couple of degrees off from TDC can lead you to believe your index is thrown off.

    For future reference, the attached photos show the degree marks on the Ficht flywheel (MSX 140 12-magnet version shown, six magnet version is similar).

    You can see the triple encoder bumps at the -30 degree position.
