Expect so. It's a Lycoming IO-360-A1B6, converted by the RAF to
an AEIO (added an oil tank thing with a ball in it that blocks off
different bits depending on which way up you are). Of course if I did
put them on, no one would ever find out I guess...but I'd rather not if
it's not "proper".

I tend to do ok running less than 75% power...actually I normally
potter around at maybe 50%...it's a 2 seater with 200hp...and I can
lean to about 5 gallons an hour. If I'm going somewhere I use more
power, maybe 7 gallons an hour. UK gallons that is. I lean until the
power starts reducing. I don't seem to get high CHT (only one gauge).

Ahh -- that's a whole different game, then. Your engine is
certificated in the U.S., though, isn't it?
