Re: **How to set timing on 76 chrysler 45 HP**
First remove both plugs. Using a thin bladed long tool (screwdriver) turn the flywheel until you find top dead center on the top cylinder. Mark the flywheel and a corresponding place on the engine block. This is zero. Now count the teeth in the flywheel and divide into 360. This gives you the number of degrees in each tooth. count back to the left (clockwise) the required number of teeth and possible partial tooth to obtain the desired advance (28, 30, 32). Mark the flywheel. Those older Chryslers were timed at 32 degrees advance but later on it was changed to 30. Either is acceptable if you use automobile pump gas.
If you have magneto ignition the engine must be running at wide open throttle to set timing. If you have points and battery ignition, you can time it static in the driveway.
Attach a timing light to the top cylinder and check timing. The advance mark on the flywheel should match the zero mark on the block. If too far retarded, or to the left of the mark, shorten the rod that runs from the timing tower under the flywheel if too far advanced, or to the right of the mark, lengthen it. If you are timing a magneto engine, stop the engine and gradually adjust the rod in increments so you don't join the nine finger club.
Since a battery ignition engine will fire at any speed, to static check timing, remove the plugs and ground them. With the key on and throttle in wide open position, slowly turn the flywheel looking for spark on number one plug. When it sparks, the flywheel advance line and block zero line should line up.
By the way, if you watch my video, there is (I think) a three cylinder engine with the flywheel marked in black marker.
