I guess enough time has passed that I can tell this story…
Once Saturday morning at CMP 2yrs ago when I was in the engine-of-the-month club, Al happened to notice that my ignition cable linkage was fubared. I was missing the little white piece so the PO had put in some spacers or something in lieu of. Al looked at it and says “nah, I think I’ve got that thang”. Al, bless him, stumbles back to that SpecE30 parts explosion he calls his paddock space and comes back with the little white threadedpiece. He says “Here, I’ll show you how it goes in.” He disassembled my perfectly serviceable jury rig and threaded on the correct part, the white plastic thing.
That was the debut of that particular motor and it was clearly weak. “God, won’t this ever end?”, I thought. I forget the saga of that particular motor but it would shortly thereafter do miserably in compression and leakdown tests and so was pulled for good reason.
At the next event I had a different engine. It too seemed week. But, I thought, maybe I’ve just gotten really rusty. Soon after I got to looking at the throttle linkage and it just didn’t seem right. IIRC the little vertical pin that rides in the black plastic piece, I mean the 1cm long pin that the cable goes thru, was missing. As a result the white threaded piece was sticking out thru the black piece. “Where the hell did that little steel rod go”, I wondered. And then I remember Al pulling my throttle linkage apart. The result was that I wasn’t getting the last cm or so of throttle movement. No wonder I had a weak engine, 2 of them actually, at 2 separate events, and they were both weak.
But like I said, that first engine failed a leakdown and compression, so it needed to get pulled anyways. No harm done.
