750 twin engine not starting

I have an 82 kz750csr twin that will not start. I thought the ignition was bad so i converted back to the old point and condenser style ignition. i followed the service manual on how to set it up. i am pretty sure that i got it dead on. It will back fire but that is it. Could the cam timing be off? If anyone knows a lot about these twins please help me out.

thanks,
Paul

Rotate the ignition advance 180 degrees and try it

Check to see the points are opening at a crankshaft rotation point near the "T" mark. You can see it under the points cover. As stated above, it is possible to get the advancer assembly on 180 out.

i have done this already. it still has not helped. any other ideas?

Check for hot spark.

Check spark plugs to see if they have fuel on them.

Check compression.
