Check the spacing on your coil, the gap may be off if it is use a business card to set the gap, push down firmly when tightening u should have to wiggle the card out but not ripping it. If thats not it check the plug. Hope this helps good luck.

that doesn't sound like an air leak. it sounds like your to rich(?).. it idles fine? and i would think your idle screw is pretty far in, yet still idling ok? pull the idle screw out, lean out the low side.(the idle will raise, but thats fine for now) lean it out till stays running off the throttle, then adjust the idle screw. do small adjustments(1/16 turn in)your going to have to do a plug chop to make sure its not too lean. did you change anything before this started happening? like a pipe or carb?

lean your low speed needle a touch.

The sweet spot is around 1 1/4 to 1 1/8 on the L needle.

Make certain you don't have your fuel lines reversed at the carb.

Check the clunk location, mine was pulled up a bit, and it did some real stressful stuff.
