Several good comments thus far. Need to separate if it is a gas or spark problem. Gas - Squirt some gas down the carb or a few teaspoons directly in a couple cylinders & crank. Coughs & sputters, then quits, tis a gas problem. Electrical - If after the test above, nothing happens, spark or timing may be the problem. Pull all the plugs. Crank engine slowly till #1 cylinder is coming up on compression (thumb over hole pressure test). With mag fully retarded, inspect piston thru hole and verify mag trips at TDC. Rotate the engine 2 full revolutions again but stop just short of TDC. Remove the distributor cap and note that the contact on the fiber gear is around the 1:30 -2:00 position, and that the wire from the upper right of the distributor heads to the #1 cylinder. This exercise verifys timing and proper wire to the cylinder. My F-12 starts on the first or 2nd quarter turn most every time. Don't need the choke unless starting in the winter. Good luck. Let us know what you found.
