Great thread AussieSteve.
Told me everything I needed to know to sort out my 48cc HT's 4-stroking (and possibly detonation?) problem.
Earlier, I figured out that I needed a leaner fuel/ air mixture, but dropping the sliding needle fully and re-jetting from 0.65mm to 0.5mm wasn't quite enough.
Lowering the float's closed position by about 2mm to the correct 21mm hang immediately fixed the problem, and I now have a 'sweet' sounding and more powerful (+economical?) engine.
Thanks!
