I don't mean to hijack but I'm kinda in the same situation. Im just in the same boat basically. I was actually looking at flat slides and maybe a regrind. I don't have carbs in the first place so finding a used set of carbs, then rebuilding themeverything else. I figure I'd be better off getting something decent. I need a throttle control and cable also as it doesn't have that. So no sence of buying two of everything when it comes time to upgrade which I plan on doing.
