<DIV>Hi Dave, this was written about fairly recently. Mobil 1 is a superb oil in its ability to not just coat and "wet out" a metal surface, but to actually penetrate the surface and bond to it. That's the main reason full size engines last and last when they are fed this stuff regularly.</DIV>
<DIV> </DIV>
<DIV>But that same property, metal penetration, is likely causing the elements of the plugs to get fouled prematurely. A glass hard coating will build onto the element, killing its catalytic properties. There's nothing wrong with the procedure you outlined. I would continue except I would change after run oils. My favorite is castor but I know Dean likes Amsoil, and others use Klotz and other oils contained in fuel. </DIV>

<DIV><FONT face="Arial Narrow" size=3>I've been running the 1.45 for a couple of months and have about 10 hours (58 flights) on it so far. The bearing is showing no signs of wear yet. I'm running 15% S&W fuel and run the engine dry after every session and <STRONG>LOAD</STRONG> it with Mobil 1; not just a few drops - probably about a tablespoonful, maybe more. I removed the integral pump and am using a Perry so probably any after run oil would do; no diaphragm to worry about.</FONT></DIV>
<DIV><FONT face="Arial Narrow" size=3></FONT> </DIV>
<DIV><FONT face="Arial Narrow" size=3>For the first run of the day, I remove the glow plug and blow out the oil with the starter, replace the plug and start it up. It usually "complains" a little for the first start, but it always runs on the second or third try. Thereafter it will flip start for the rest of the day.</FONT></DIV>
<DIV><FONT face="Arial Narrow" size=3></FONT> </DIV>
<DIV><FONT face="Arial Narrow" size=3>It does eat plugs, though. They seem to last only about 10-12 flights. (OS F's) Any cure for this?</FONT></DIV>

<DIV>
<DIV>That is terrible bearing life from the set-up Keith. Mine lasted about 100 hours (452 flights) until the pump finally went, which meant the engine ran lean for several flights and then the bearing went.</DIV>
<DIV> </DIV>
<DIV>Bearing no 2 has run all season and has about 32 hours on it so far, or about 150 flights; same engine with a new pump.</DIV>
<DIV> </DIV>
<DIV>Fuel is the same cool power I spoke about before: 50:50 mix of 5% CP and 30% heli mix, plus one ounce of Klotz Pro per gallon</DIV>
