It has been a while...say 20 years or so since I flew control line. 

My neighbor is trying to get me into RC, and I broke one plane already...

I have some models from when I was younger.  I learned today that my Cox 049 engines have the reed glued in place, and I now have one model running extra strong.  I also learned on that engine that the oils in the fuel congeal and can form a plug in the fuel nipple.  I ended up using a hat pin to push the plug out after removing the needle from the valve, and the fuel line.  Two more Cox 049 engines left to clean up...

Now, I have an Enya 09, similar vintage say 1975-1985.  Fuel feeds to the engine just fine.  Glow plug heats up very quickly.  I can get it to bark at me but not to run. I am starting with a needle setting of 2 turns out.  When I choke the carb it will draw fuel very readily.  When I get it to bark it draws fuel, but does not stay running. 

I am hand proping.  I usually use bare fingers, but also use a chicken stick.  I don not have an electric starter, but my neighbor does.  I am using old fuel (old enough to go drinking, 21 years old) that runs fine through the OS40 from the trashed RC plane, as well as through the 049, so I have to believe it is good.  The can says 5% nitro Fox fuel, but I am told by my parents that it is refilled with higher nitro fuel. 

I need suggestions on where to go from here.  I can get some fuel and the electric starter from my neighbor, but he is working straight through to next weekend.

Is this a new Enya 09 that needs break in ?

These is an iron piston engine and  Enya makes engines with very tight piston/liner that require some work to get it to run for the first time, but once they are broken in they will suprise you with its power and easy to use.

The Enya 09 has a lot of torque, mine works best with an 8x4 prop.

If there's a reed-valve Enya, it's a collector's item.

You should be able to see the crankshaft through the venturi, and see the timing hole go past.  It should start to open as or sometime before the piston starts going up, and close as or a bit after the piston starts going down again.

Are you saying that you had the needle valve all the way out and the engine did not run?  Given that it draws fuel when you choke it, if you can't open the needle valve enough for it to run then either your fuel needs renewing or the hole in the spraybar is plugged.  Given that your fuel works in other engines and this one doesn't seem to want to go at all, I'm betting that your spraybar hole is clogged.

Thanks for the welcome.  I need to figure out a no-wheels 1/2a stooge too.  I don't think my wife will launch for me...

3 CL airplanes, 3 working engines on them.  Just ran the other Cox 049...in reverse for 2 tanks before I could get it to start forward.

The "spare" Cox 049 has a bent up needle that I can't get to operate smooth enough.  Guess I will have to order parts from the new Cox engines.

Now to set up a stooge or get my neighbor or wife to help. (or all of the above)

If you have a plane that pulls hard enough try a "sleeve launch".  This guy's system is way too complex for 1/2-A -- I use a folded-over piece of cardboard held to a chair with a vice-grip.  All you need is a sleeve that the wing fits into well enough that it doesn't rattle out by itself.  Then anchor the sleeve to the ground or something heavy enough that the whole thing doesn't tip over when you pull the plane out.

Maybe someone is reading this who knows of a collection of shots?  Or maybe you could post a request for pictures of people's systems.

The one requirement is that the plane reach flying speed before it hits the ground.

I used a towel a piece of plywood, some foam because I was flying a "little wizard" (I set it so the foam could slide out with the wing), needed to brick up one end so I was starting "up" and 1/3 tries I got a flight in.  3 good flights, but the plane is not as responsive as I remember...and more beaten up that I remember.  I think I need a new elevator.  The engine appears to be the most tame variety Cox made, and is probably off a plastic RTF originally.  (My "spare" is the same engine)

Tried my "lil jumping bean" with a more open ported Cox engine, and made the mistake of leaving the plywood blocked up...straight into a wing over, looped into the ground and a broken motor mount...looks like an easy fix at least, but not today.

I don't remember getting this dizzy 20 years ago either.  I also remember being able to do a lot more stunts with the "little wizard" than a wing over.  Probably related.

I chickened out about flying the 09 on 30 ft lines...
