<VV> Engine won't Fire

[Ken Pepke]

OK, assume the rotor cap is in place.   How does the engine crank with the starter?  Does it sound like it has compression or is it really freely spinning?  Check the 'draw' at the carb air horn ... Perhaps the lifters are adjusted down far enough to keep the valves from seating.
