Hi Guys,
Given that the "chain saw" like go carts are usually half to full throttle when in use...
Nick, do you think it would be a good thing to place the groove a few degrees off the idle position to get more of the "upper throttle range" for the chain saw?
Also, when I did my generator (up to 17 hours compared to the 6 hours prior) I gave it a 4 to 8 smile rather than the full sweep. You could start with that... test and if the results are good stay with that... if you think you can get more, finish the groove to a full sweep and test again.
Just some thoughts
