RE: OS change to Nickel Plating instead of Chrome?
Chuck, I have an old Webra .91 that has run many hours as a Glow engine and for about the last 6 years as a Diesel, I referred to it one time as an ABC engine but was corrected that it is an ABN engine. To this day you cannot begin to turn it over by the prop driver like you can a lot of other engines, it simply does not leak off.
