Is your ignition working; check each plug wire with a spare plug to see if it's firing. If that's OK, the ignition timing may be wrong.

set the engine back to TDC and reset the distributor. Not much you can do about that.

Here's a procedure for setting up the distributor timing on a SOHC motor:Remove the distributor and the oil pump. Now you need to find Top Dead Center (TDC) for the COMPRESSION STROKE in order to time the ignition distributor. To find TDC, remove #1 spark plug. Have someone tap the ignition switch start position to slowly crank the motor while you put you hand or thumb over the spark plug hole. When you feel the compression, stop. Now look down at the timing pointer at the front pulley. It should be pointing to ZERO. If not, manually turn the motor clockwise or counter-clockwise by hand until it's pointing to ZERO.

The oil pump uses a shaft to turn the distributor. Insert this shaft onto the oil pump with the punch mark on the shaft lining up with the hole on the oil pump (below gear). Install pump/shaft to block. When installed the end of the shaft will look like a "D", when looking into the distributor hole while standing at the drivers side front wheel well. Actually, it (the "D") will be more of a "11:45" position, NOT quite "12:00"; if not, then remove, and reinstall until the above position is obtained.

The KA motor firing order is: 1-3-4-2. This is at the distributor cap.

Determine the #1 plug wire location on the distributor cap. Mark that location on the distributor body. Now insert the distributor into the block so that the rotor ends up pointing to the mark you put on the side of the distributor body. You now are timed close to correct; you should be able to start.
