The idle is great, top end is pretty good, but the mid range (just after idle) is struggling severely. What in the world is going on here??
Notes: I've cleaned the carb (idle / main jets) twice now, as well as sprayed down the bowl with carb cleaner and cleaned the throttle slide. There's no holes in the diaphragm and the air mixture screw is hardly making a difference at all. What's the deal?
** EDIT **
My friend (the previous owner) said that, before we cleaned the carb, it would accelerate fine but that when driving sometimes the carb would flounder around, become laggy, and sometimes backfire.
