yeah set it to the pointer. also when was the last time you did a full tune up, cap, rotor, plugs, wires. could be time.

Try using a timing light. Much more accurate than a mark in the block.

You said carb, so I am thinking an accelerator pump problem. You need to see if both pumps are pushing fuel thru the discharge nozzles when opening the throttle.

fuel is comein out of both i am thinkin bout tryin a smaller carb

I have a 750dp and works good (mechanical secondary). I'am almost sure something is wrong with your carb.
