I did my 25 hr. Rotex inspection today and my forward cyls. 1 & 3 both had rich looking plugs but my number 2 & 4 plugs looked fine. Any ideas what the problem could be? Or is it a problem?
Thanks,

From what I have been told it is a sign that the front two cylinders are running cold.
Interesting comments about auto gas and sooty looking exhaust pipes. I don't see this on any of our EFI equipped engines- Subaru, Rotax, Suzuki or Lycoming. Pipes always look nice medium tan colored around here.
Your company doesn't produce EFI for Rotax anymore...why not?
