I adjusted the valves today, but had a ***** of a time getting TDC lined up (on a 92 250X). off the compression stroke it rides to the T mark easily, but on the compression stroke, the piston wants to fall back down (yes the plug was out) I had to leave the ratchet on the flywheel bolt and lean it on the shifter to prevent the crank from moving.. any ideas on doing that easier?
