   With the plugs out, You should be able to push/pull on the belt to tension it and turn with fan blade. I usually push in to force in groove.. A pry from under neath at the flywheel will probably be more precise.

	Numbers 1 and 4 will be TDC when the marks line up, one will be on compression stroke, one finishing exhaust stroke. You need to be sure # 1 is on the compression stroke by feeling pressure via the spark plug hole or checking valve rock (requires removing valve cover).

	Jack up one rear wheel and place the transmission in the highest gear. Turn the wheel until the timing marks line up. Leave spark plugs out.

	When the setscrew on the crankshaft pulley is straight DOWN, you are at TDC on #1 cylinder.

	Bump starter with finger in plug hole until you get close, then turn with flywheel until marks on flywheel line up. MACK

	New member, first post, and newbie working on old tractors. I just got a rebuilt magneto for my 49 WD and am ready to time the engine and install the mag. Problem is I have a crank, but no stem coming out of the crank hole to attach the crank to. Any ideas on how to spin the motor slow without a crank? I've pulled all the plugs so there'll be little compression resistance. I've tried pulling on the belt, but no luck. Guess I'll try a wrench on one of the pulleys next. I'd appreciate any ideas. Thank you.
