I was thinking about a poor man's throttle for this engine, of course a small round BIX burner would be the way to go...But what if took a thin wall brass tube sized so it slip fits over alcohol burner wick spout? Pull out enough wick for larger flame fast run, then slide the brass tube out to cover some of the wick for smaller flame slow run?..might be a little touchy and might need a handle to help get at the sleeve without burn fingers, just a thought....
