Balky A-block

[terrford]

I'm have an A block engine for my '30 coupe that I can't get started. I bought it rebuilt and low mileage. I got it from a friend so I know it ran at one time. I have installed all new ignition and a rebuilt carb. I have set all spark gaps, timing and carb adjustments according to the Mechanics Handbook (several times). I am using fresh gas. I have compression (using the time honored hand over the plug hole method). There is spark right down to the plug electrode. I have tried various adjustments to the spark advance.

The doggone thing won't even spit out a smoke ring...

Any suggestions will be greatly appreciated.

Thank you,
Terry
