I have a TMS38 that I bought to use on my CR125 Micro Sprint car. It is very rich no matter what I do. I have it jetted down to a 280MJ, and the needle is dropped all the way, and it's still too rich. It idles OK, and is'nt too bad up till 1/8 throttle, then it just 4 cycles. I have been using a VM36 carb, with a 350MJ. I don't see how a bigger carb would need so much smaller of a MJ. I have tried to find out what the float hieght should be, but can't find it anywhere. Also when measuring do I go to the bottom of the floats, or the brass piece that rides on the floats? Any setup :bang: help would be appeciated. :bang:
