Possibly the advance isn't functioning. Most likely the vacuum advance, I 
would think. Check the hose first, and then the diaphragm would be your 
next suspect. If you disconnect the line at the carb end and suck on it, 
you should be able to see the distributor plate move (that is if you 
remembered to remove the distributor cap). If it doesn't, and you get a 
mouthful of funky tasting air and hear a whistling sound, the diaphragm 
is toast. I'm afraid the blighter is a little pricey, too. Check the 
manual for instructions on disassembly. Good luck.
