If you look down the carb while pushing the throttle with the engine off you should see a good shot of fuel. If not you probably have a bad accelerator pump. It is fairly easy to replace. You will probably need to buy a whole rebuild kit to get one.
The other thing I would check it point gap. Should be about .017 - .019 with the point rubbing block on one of the dist cam hight points. If you have or can borrow a dwell meter set it to 28-32 degrees.

The accelerator pump is a common issue with that style carburetor.
