A few years ago, I pressed a "bench run" only like new OS .61 RF engine
into service in my old Super Kaos. It started, ran, and idle nicely....but on
landings the engine would die out. I adjusted the carb and played with it,
I knew it was set perfectly. Finally, after a few dozen of these dead on the
runway episodes I pulled the plug....yep, a darned idle bar plug was the culprit.

Blocking the fuel from the fire would cause the engine to die out after about
20 seconds with the plane coming in for a landing....time after time, after time.
I felt kinda' foolish when I discovered the idle bar plug, because I had overlooked
it when I installed the engine.

I got a wonderful toss out of that idle bar plug....I got about 50 yards with it
with a beautiful end over end spinning rotation.

Like I said in my previous post, I had it "proven" to me that my K&B would not
only run better, but would idle better with a plain ol' K&B 1L plug, and it was so.

I wish I had a nickle for every engine that was destroyed by an idle bar plug,
when the bar fell off. Most everyone that has been around awhile has either
had this happen, or knows someone who had this happen to them.

I don't know a thing about MDS engines, and what they run on.

The baffled piston/idle bar story is an Old Wives tale....it ain't so.

FBD.
