New spark plugs?
Did you test spark with a spark tester? should jump 7/16 gap strong.
Carbs clean/rebuilt?
Choke closing?
Fuel pump working well?

Carb throats wet? i.e. getting fuel to main venturi?

Only other thing would be timing.

Fuel, Air - in proper ratio
Spark - at proper moment
All those parts and thats all it takes to run.:eek:

I know, I also wish it were that simple.

Timer Base?

A proper spark test is a good idea. You would not believe how easy it is for spark to fail Under Compression. Autozone about $10.

You could have someone spray fuel as you crank, but keep a fire extinguisher handy. Motor backfire bites!
