First top up the dashpot as said by woody (this is always a good thing).

Then just maybe you should tune your carb, the mixture might be out.

If you want to tune your timing, invest in a timing light (they're like 30 pounds or something).

Probly find its the vacume advance is broken on the dizzy if it heasitates on accelleration. Pull the black straw off the carb that goes to dizzy, stick the end in your mouth and suck gently, then stick your tongue over the end. If it sticks to your tongue its ok, the vacume is working, if it doesnt stick, then looks like a trip to the scrappy...

If thats the case, then get and electronic dizzy instead of crapy points...
