Nothing new here. Except this time I repaired the broken wire and the gauge now runs backwards. I've never seen that before, but I know others say it is characteristic of a broken wire as well, so I pulled the plug off again and did a continuity check to the rear RPM gauge. Everything checks out. Good continuity, no dry solder joints, but the RPM gauge continues to run backwards. Anybody got an idea what I'm missing? Dave. ________________________________ Message 2 _____________________________________ Time: 07:41:58 PM PST US Subject: M14PEngines-List: Initial start after depreservation and break-in From: "KT247" This is my first post in this forum and want to thank Matt for maintaining it. I have an M14P that I'm in the process of de-preserving. The motor's currently hanging from a hoist with its motor mount attached. As I'm draining the oil from various places, I found some paraffin in the cylinders. What I'd like to do is flush the motor and cylinders out with something. At this point I'm not sure what to use. I feel the safest thing would be to use some Aeroshell W120 oil diluted with 100LL. I don't know what chemicals would adversely affect the seals in the motor. Looking for recommendations. I have read through all the task cards in the maintenance manual but haven't found anything regarding a break-in procedure. Does one exist?
