I found out recently that the mixture screw on my stock carb needs a special tool to change the setting. I thought about going to a stock crf 70 carb instead but i was curious to see if there are other 50 years where the mixture came with a normal screw that anyone can change, and if so, if i could buy that screw and just throw it in where mine is now.
