reeds, coil or woodroow
maybe your flywheel become loose? That Woodrow key sometimes shears off. If that is not the case try a different coil, testing for spark and getting spark when the plug sits in the cylinder's head are 2 things.
If the plug gets wet you get full, if it does not get wet you don't get fuel. Your reed could stick and won't let any fuel through. Take that plug off and kick it a few times, than remount the plug and start. Hopefully that helps.
Good luck
