Running to lean or to rich can cause this problem. Is it running hot if so would indicate its to lean.

I didn't think an engine with only 1 ignition point could misfire....can it, it sound like its too much or too little fuel

Lean high side. When in doubt richen it, a rich engine runs slow and boggy. A lean engine runs hot and irregular. Whatcha want to do is balance the bog with consistent running. If your engine don't bog a little while running slow... Richen it. If it rips then stalls...richen it. If it sounds funny..... Richen it! Your little engine runs on gas don't starve it.
