    Cheers, Peter, never having seen the plans for the Tiger Moth, what you are saying makes absolute sense.

    Hi Geof I read your post with interest as I have built the cirrus moth 40, again DB with an SC52,  measured from the plans the down thrust is 4.3 deg and the side thrust is 3 deg.  Weird I would have thought that they would both have been the same as they are so similar. Anyway the cirrus flies wonderfully with the above thrust lines.

    Thanks all, I did strip down the engine last night, and I did look at the OS52FS on you tube, ( thanks Engine Doctor). I was relieved at the ease. (I am a retired physicist not a mechanic) What I found was the bearings even the reduction gear ones on the cam were perfect, everything piston/ liner etc. There was a build up of carbon on the exhaust valve surface and stem and also the exhaust port to the silencer. So Jon and Peter were right . Iv'e cleaned it up best as I could , I am the sort who looses minute things so I didn't actually remove the valve. I have built it back up and sucessfully run it this dinner time. The only awkward bit was adjusting the "bleep bleep" valve /tappet clearances. So all the black is/was carbon from the exhaust being carried by the excess oil. I might run it without tank pressure when the weather is better. If you are interested in the plane it is on you tube (Rogers Eindecker) it aint fast !!!! Again thanks all

    Thanks very much for that, I will have a play. I have never stripped an engine since I was a kid. Must remember to have a clean/clear bench area ,now that is difficult !!!!😕

    HI all To recap I never use castor based fuel even in 2 strokes, always whatever engine, Irvine Contest 10. I am not a needle valve tweeker, set it up, peak revs, back it off and ensure tick over is smokey. I am thinking something seriously duff ( a polite word!!). I first noticed it when I noticed "dirt " in my fuel bottle, I use exhaust pressure to pressurise the tank and drain off at the end of flying and run off the fuel . So bits were getting from the exhaust into the tank. So which bit do I start on main bearings. Or the head as suggested? Seems odd for once to try and repair an engine rather than search for the bits and buy new. Edited By Roger 2 on 25/03/2015 13:55:56

    Hi all, The motor is mounted inverted in a WW1 type plane and has always run well, I have always ensured it was running rich, smokey on low revs etc. I have never run it lean, the plane is a typical WW1 lots of wires and wind resistance so the motor has to work fairly hard in a wind. It has also started to change engine note in flight. Suggestions on where to start and what to dismantle first, I am a reasonably mechanically minded "crinkley." cheers Roger

    Hi all This is my latest  model it is a Top Flite Elder 40. I didn't like the suggested decals etc and so made it up as an Eindecker. I am pleased with the result and   ( I think )   it looks good in the air. Edited By Roger 2 on 13/08/2014 10:24:05

    This is my latest plane an Elder 40 as decorated as a look-alike Eindecker, landing at my clubs field.

    I think slope soaring is a superb extension of model flying. We spend 3months or so each year in France and I always take a glider with me. My all time favourite location is the Dune du Pyla, I could just sit there and enjoy the views. Roger
