More weirdness I don't need. If I'm gonna have a four stroke I want a crankcase oil sump and straight gas, preferably with EFI.

anyone successfully run a 2-stroke lean mix through a 4-stroke motor (lawnmower) and for how long, or did you have problems?
I have been running 37.5:1 mix through a Honda mower & a Makita 4 stroke blower for about 6 years. The Honda gets used at home about every 2 weeks & the Makita is a work tool that gets used daily.
I've had zero problems so far.

Is Stihl now moving away from the 4 mix engines? Last time I looked at the huge display of them at Rural King every single one was 2 stroke, including the large brushcutters.
