Ben Buckle Elf
Recently built the Ben Buckle Elf. Having a heck of a time to get a decent idle with the inverted OS 40 four stroke..seems to bog down no matter what I do to the low end adjustment. Tank is as low as possible. This engine (new) runs and idles great on a test stand upright.
Anyone have a similar problem with inverted engines. It has the OS F plug.
