First time engine build won't fire

How to set your timing.

1...Remove no1 plug, stick your finger in the hole and bump the engine until you feel compression on your finger

2...Wrench the engine CW from that point until you get the timing marks set on about 10-15 BTC. Don't allow the marks to go past and "around once" from step one

3....Pull the cap and see where the rotor is. It should be APPROACHING the tower contact for no1. Position of the distributor or drive gear DOES NOT MATTER. All that matters is that the rotor is coming to wherever the no1 wire is plugged into the cap

4......If you have a magnetic dist. set the dist housing so the reluctor is about centered in the magnet. YOU CAN CHECK timing on the starter with a light, but don't crank forever. Two people works better. Once you get good at this (magnetic) you can actually hear or rig a gap and see the spark. With the dist loose, retard (CW, SB) the timing some, and then move the dist advanced (CCW, SB) until the spark "triggers." By moving the dist CW, then CCW, to the point of "snap," and being more careful each time, you can get the timing close enough to run

5.....Since you are having trouble, might be wise to check that you actually have a nice hot spark. Ground a screwdriver with a clip lead, and hold it right at the top of the coil tower or "rig" a test gap or plug to the coil tower. Crank the engine USING THE KEY. With a solid core coil wire or the grounded screwdriver, you should get a hot, fat spark at least 3/8" long and typically 1/2" long
