Engine shooting oil into muffler

[ILENGINE]

Congrats on the repair. I learned something tonight as I never heard of a carb sucking oil. :smile:

It wasn't a case of carb sucking oil, as it was the carb was leaking gas into the crankcase, and then when running was pushing the oil/gas mixture out of the crankcase, and into the carb, where it was being sucked into the cylinder and burnt.
