Re: 1st build and rough running
I agree with Maurtis, try lowering your needle 1 notch.
If rich at full throttle then means you need a smaller jet.
But wait till break in is over when you switch to a regular oil ratio, things may get better, when more gas gets into the cylinder compared to oil.
I love my Motor Bicycle, I love Beer, I'll try not to like them both at once.
