What part of dist. to run when adj timing (49 B)

As always, it's appreciated.

It is pretty simple in theory. Like all four cycles, the piston comes to TDC (top dead center) twice for every time the magneto or distributor rotor goes around. ("B"&"C") The left side of the engine has a hole in the bell housing where you can see the timing mark on the flywheel. ("WD" &" WD45") The timing mark is found by looking under the flywheel housing for a small hole possibly covered by a small plate held with two wing bolts. The FIRE mark and the TDC mark are located on the flywheel through this hole. Use a little light colored paint to make seeing them much easier.

5. The Rotor should now be close to a lug in the dist. cap. To determine this, make a mark by the #1 spark plug wire on the dust plate that is under the rotor.
5. Now take the rotor and dust cap off then turn on the ignition.(Be sure point gap is .020)
6. With the ignition on and distributor clamp bolt loose turn the distributor to close the points. 7. Then back until they just open and you see a spark between the points. 8. Tighten the distributor clamp bolt. You now have the engine timed to fire at TDC when starting. 9. Install the dust cap and rotor and make sure the rotor still points to your mark on the dust cap. 10. Next, remembering the direction of rotation install the distributor cap and #1 plug wire in the hole the rotor is pointing to. Then #2, #4, #3 in the same direction the rotor rotates.
11. Time it with a timing light at over 1/2 throttle (so the distributor weights can advance the timing) and adjust the distributor so the FIRE mark is centered in the hole.
I hope this solves your problem. Duey
