Spark plug lead fouling issue

[Yooper Rocketman]

............. The Shell paper adds another procedure of interest, 1800 rpm for 15 seconds before shutdown....

Anyone perform this step in their shutdown procedure?

You don't want to do that with a turbo!

I didn't want to do it to my NA IO550 either...!

Never heard of it, either. My O-360 plugs stay pretty clean just leaning hard on the ground; it's only stumbled and tried to die twice, the first time when advancing the throttle to pull from grass parking back onto the taxiway. Push a little richer and it smooths back out, get going and lean a little more.

 

Some annuals I hardly get any lead out of the plugs at all.

Just got back from the Aviall conference today. The Champion tech rep did a presentation and stated emphatically that he recommends 37BY's to anyone that needs a hotter spark and does not want to run fine wires.

Considering the recent bad publicity about the Champions, he should have recommended that everybody buy Tempest!
