OK...I sprayed some carb cleaner around the intake and carb (only a minor fire....just kidd'n).

I didn't notice any changes.

I switched the advance hose to where you suggested, but noticed no difference when I road tested. I also checked the timing with the advance hose plugged and put it at about 10. I road tested again while changing the timing to nearly every conceivable degrees with no change to the bogging down of the engine on flooring the gas pedal at low and high speeds.

Again, at about 40 mph, I floored it and it bogged down severely, but when I downshifted, it took off like a rocket. It just will not pick up speed without downshifting, unless I gradually press the pedal.

Also, from a standstill, I can't even take off when flooring it (no tire spin whatsoever). If I hold the brake and try to spin tires, the engine just bogs down and won't even try to spin them.

How can I test to see if valves are sticking or working properly?

Thanks again.
