Resurrecting glow engines from the 90s

Hello all.

I'm getting back into RC again after being active in glow sport flying from 1992 - 2000. So many things have changed, but I'm hoping I can use the planes and engines that I already have (transmitters and receivers are another story).

I have 3 OS engines (.40FP, .15FP, and a ..48 Surpass 4 stroke) that have great compression and turn over. Any suggestions on what (if anything) I need to do prior to attempting to use them again?

Thanks.

Aehm... Fuel and starting gear maybe?

If they have compression and turn freely, just start them, and keep them a bit rich for the first few minutes...

That's all I would do...

If they turn over freely, prime and run 'em, if they're sticky, flush with alcohol or fuel first.

On the 4-stroke you might want to check the state of the ballbearings and also lubricate the camshaft etc before the first start.

The plain bearing 2-strokes are easier I guess, not so much that can go wrong, but it would be fairly easy to take of the backplate and see what it looks like inside. If they were run on full castor before, then there is a risk that the conrod is stuck to the gudgeon pin, for instance. In that case you are better off freeing that up before running them.

That is a good one... I did not think of that, and I should have...: exactly that did cost me a nice OS heli engine a few months back....

Kris is right: check that, better safe than sorry!

Th stuck rod to the gudgeon (wrist) pin is nearly always overlooked but it must be free. All that's needed is to remove the backlpate and, with the piston at BDC, hook a small allen key behind the rod as far up inside the piston as possible then try pulling the rod along the pin with the allen key and pushing it back with a finger. It should slide freely. If not, with the engine inverted, fill the inside of the piston with either fuel or preferably acetone and keep trying to move the rod. Once it moves even the slightest then it'll free up very quickly.
