Allo Ernest
Looks like a good buy. Do the rotors rotate freely?
I flew my 1986 - 13B with a carburator at first. The engine ran
very well, but I could never devise a way to lean the mixture at
altitude. My engine would consume 30 litres/hr, from startup to
shutdown. (2.5 hrs flights.) When I removed the carb and
installed a Holley low pressure injection system, the fuel burn
went to 28 litres/hr. Quite probably less when I will learn to
lean more aggressively.
I am still flying with a Mazda 1985 electronic ignition system
and am well satisfied with this system. Quite maintenance free.
I readily agree that the more recent electronic ignition and fuel
injection systems are well worth the investments.
Believe me, you will love flying your rotary.
Good luck and be patient, you will need to.
Yvon.
