Paul:
Next time you talk to the Mazdatrix guys, thank them for the great job
they did on my engine.
It's been on the plane for four years now, I haven't taken it off since
I installed it in Palm Springs June 2001.
375 hours on it now, never a problem. 540 hours total.
It did start leaking oil from somewhere around the front cover on the
right side after about 1 year. I've never been able to locate the source
exactly. But it's a low seepage that I just live with, not worth taking
the engine off for. I have to add a quart every 3 to 4 hours, but some
of that loss is injected oil - two remaining oil injectors in the
engine, the two from the intake manifold have been removed.
I recently completed a round-trip from Oregon to Kansas, the engine
continues to perform flawlessly. My biggest problem travelling is
finding mogas. I can't burn 100LL, it will foul my plugs every time.

What steps can one take to be sure that he does not need to use mogas?
Don't want to be limited to only mogas.

The engine runs fine on 100LL. 100LL just slowly fouls the plugs and
slows the response time of the O2 sensor which is not a real problem
as Tracy does not use the O2 sensor. Perhaps for initial tuning.
Run some auto fuel once and a while and the O2 sensor and maybe the
plugs will recover.

I met Perry recently and he notice plug fouling quite rapidly when using
it. He has not done anything special to the motor. No porting, etc.
Does porting help? Would the renesis have less trouble using 100LL?
What type of plug is most recommended?
Rick Irwin
I don't think porting would make a difference. Perry is using 2nd gen stock
ign system and not the one transformer per coil Tracy is using. That was the
case the last time I saw his engine.
I have no idea what plug most are using. Some run hotter plugs
than others. I am sure that will make a difference.
