I have always been lucky with my 70cc engine I guess. I spent the most part of today attempting to get a 48 to run well for a friend.
I have 2 here a Rock Solid with 1000kms and a leaking crank seal, and a Zbox that is about 1 hour old. As I have many carbys and plugs here I have been trying all combinations with no luck. I have tried jet swapping, mixture settings, swapped plugs and plug gaps. I just can't get these things to sing. The plug always reads OK but never any 2 stroke action, and never any bottom end power. At times I can get it to scream up high. Though I then turn around to go back home and it won't do it again? They start very easy and will idle.
The only thing I have not changed is the coil and plug leed? Could this be something to check out?
I am a mechanic by trade and can tweek most things. But these have me stumped?
Any clues????
