The needles have to be screwed in so far down in the carb. It seems like 1 hour of a turn does alot!! The carb slide is notchy and wiggles, I am thinking that I need a carb. I got alot of RB concept carbs and I got some OS v-spec carbs. Which carb should I use???
I've heard some of the early Go's had a different taper on the needle's and one hour was a big adjustment. If you haven't put new o-rings in the high and low speed I would do that first.
