582 - Oil in carb float bowl?

[GyroPaul]

I have a bluehead 582 with oil injection and about 150 hours, and I recently started having oil in the float bowl of the rear carb after it has been sitting for a few weeks. Wondering if anyone else has run into this and what the cause might be? And no, I won't be getting rid of the oil injection system. It still runs great but smokes a little at start up until the bowl has been flushed out.

the check valve that feed oil to carb. is sticking, take it off and clean it or may need a new one!

It is the check valve on the oil injection system. mine did the same thing, just dump the bowl before starting and it is OK, yes it should be replaced, about $30, get new clamps and hose at the same time.
