Re: Ideas how to contain carb spit-back
i wipe mine with a rag every 5 miles or so.
actually, i don't think there's a cure for it. if you got a bigger filter to soak it up, it'd just get saturated and have to be cleaned out more often to provide good airflow.
the right mixture helps a lot. i use 100:1 opti 2 oil, and the oil doesn't clog up in the filter and leak out as much.
