You need that spring and collars plus a special slider that slides on the linkage. Just get that ofna one man its the best way to do this. Or you have to make one. I made mine on my mt2 out of a hunk of plastic a small piece of antenna tubing 2 collars and a stiff pen spring. Ill put my pics up righ away. If yo dont have the springs and collars your going to wreck your carb because its going to try to close the carb when you brake.
