Mark Im glad to hear that your problem has been found!!! Looks like I hit the nail on the head with that one......:) ----- Original Message ----- From: "Mark Jones" <flyk...@wi.rr.com> To: "KRnet" <kr...@mylist.net>; "Corvair Net" <corvaircr...@mylist.net> Sent: Friday, December 01, 2006 10:14 AM Subject: KR> Ignition problems / Hiccup
> Well guys, the smoking gun on my ignition problems has been found. Last > weekend, at the request of William Wynne, I removed my distributor and > shipped it to him next day air for him to test my distributor on his > machine. What was found was that the shaft was worn extensively at the > upper bushing. It was actually oval shaped at that spot. The bushing > itself showed no signs of wear. This allowed the shaft to wobble as it > turned which would create the hiccup in my ignition when that sweet spot > appeared. This distributor had approximately 150 run time hours since I > built the engine with 134 of those being actual flight time hours. The > cause for this wear is speculated to be an inappropriately clearanced high > volume oil pump which I installed on my engine.
