Re: Still Wont Start !!!!!
So compression is good, youve gapped the points within 012 to 016 thou. Are you familar with how to do this? You have to do it twice, rotate the crank, etc etc. Did you check static timing with a continuity light? Static timing also has to be set twice and on a different mark each time. The left point set needs to be set static on the F1 mark and the right point set needs to be set static on the F2 mark. These marks are 180 deg apart on the crank.
Next, after cranking, are the plugs wet. Youre sure youre getting fuel into the cylinders??
If everything above is fine, its very possible youre just not familar with how to start it. Turn the fuel petcock to prime. (The petcock handle will be forward) Wait 15 seconds. Leave the petcock on prime. Pull out the choke about 3/4 and hold it in that position. Turn ignition to on. DONT touch the throttle. Press starter button. It should start within a couple of turnovers. If it starts, continue holding the choke, switch petcock to run (petcock handle will be pointing down) and DONT touch throttle. Regulate engine rpm with the choke. In a minute or two, you can start reducing choke a litttle at a time and adding throttle to compensate to retain rpm.
After trying the above, let me know what the result is.

There is another small item to consider.....are the plugs firing in the correct order. You have two coils and they each fire two plugs.
One coil fires plugs 1 and 4, while the other fires plugs 2 and 3.
It is possible you have the wires on incorrectly, and that would mean nothing but wet plugs, as it would never fire at the correct time.
