You sure it wasn't out of a Cessna because that is the one I got a the other guy in our club snagged the other. Get this-the local auto parts store had those plugs at their warehouse and had me 2 the next day-no idea why they would stock them but was pleased they did. Yup-$15 ea. Hopefully all my switches and batteries will be here for the wknd so I can run it, still about a month away from flying at our field. 25/32:1 sure sounds thick. I use Pennzoil Air Cooled at 40-45:1 (not to get into that debate). We'll see and post what happens.
