Yep, good to see you still around. Don't always go by how well the machine runs. A lean engine will run like a scalded cat until it blows up. Not saying thats where you are. From knowing your set up you are probably pretty close if not right on. If your plugs are looking good and it runs well you won't hurt anything. Once you get to that point only way to tweek it in perfectly is the dyno.Just a tad rich won't hurt anything either as long as you aren't getting soot. With no soot you are burning the fuel so are in no danger of loading the oil with gas or washing the cyl. walls clean of lubricant.

I learned all I need to know about life by killing smart people and eating their brains.
