oil fouling on the 750
i have a 94 750xi with the dual carbs. I rebuilt the carbs and all of that good stuff but recently the front cylinder is LOADING up. this isnt a wet plug, but it is oil. The mag plug is covered in tar and is sooty black after about 2 minutes of runtime, while the pto looks great. What would cause this?
(it still has oil injection)

Not sure. Swap the oil lines at the pump and see if the problem moves to the other cylinder. Make sure you get any air bubbles out.
