Mine is clean burning on startup. And only shows fuel smoke when getting on it. And need to turn the smoke screw back on it to cut part of that out. As it leaves 2 trails of smoke at every shift or when pulling. Will blow smoke 30ft behind me under a load.
Is yours fuel smoke or oil smoke? Wondering if you have something leaking oil down into the motor and taking a while to burn it off? Or fuel and having to burn it off?
