Hi Guys,
The annual on my friends T-craft has me digging again for things to improve and make better. This T-craft too suffers from the top plugs very slightly rubbing the cowl canoes. Enough that it bugs me and will eventually cost him a wiring harness. I found another solution that is approved. Champion 62S spark plugs are approved for the A series, and C series, although NOT the C90 & O200. I bought some on a whim cause I found them dirt cheap, and as expected they are sorter than the UREM40E's that are currently in the engine. They have 5/8" tops, and the nut potion is a meaty 1" diameter. Just enough to keep things from rubbing and give a little breathing room. The 62S is a shielded single electrode plug (ala car, lawn mower plug). Going to run them in the top and see how they do. Heck, as cheap as I got them NOS in cosmoline if you change them every time you change the oil, they'd be a steal! The weather/wind is supposed to be good enough here to fly Monday, I hope to put a couple hours on it. I'll let you know the results as far as running goes, but I'm sure they'll do fine.
Below is a picture of a 62S on the left, a UREM40E in the middle, and an AC88 (C26/M41E style) plugs for comparison. And the second is a picture of the electrode. The other 2 are self explanitory.
Heck, cutting open 60+ year old cosmoline gauze and the origional boxes was worth the price I paid if I use them for decoration. I bought some extras, and now have access to hundreds more.
