I guess I lost it, but this was years ago. The last time I tried to fly it was about 12 years ago. I tried to fire it up for my older son (now 25) and it did the same thing as now. When I came across the plane a few weeks ago with my 10 year old I thought, "I'll bet is was old fuel, that is why it wasn't running". So I was all fired up to fire it up.
When I found that the glow plug wasn't glowing, I bought a couple on ebay. But then found that when I got them the old one was ok, but the battery pack had a problem. I found that I was missing the darn head gasket anyway! So, with the new head gaskets and glow plugs I picked up some fuel on Saturday and tried to fire it up, nothing. So I have to assume that I pulled it apart back 12 years ago and lost the reed and the head gasket.
Anyway, the minute I found out that the reed valve was gone I called my oldest son and told him of my discovery and why that darn thing didn't start up that day.
In cruising eBay I found a lot of cool stuff that brought back memories. First off, the motor in this plane that I have has a plastic back on it where the reed valve goes and a separate furl tank that is mounted on the plane. The one I flew as a kid back in the late sixties early seventies had a fuel tank that was metal and on the back of the motor. Why on earth did that change that is beyond me, seems like a cheaper yet better way to go.
P.S. A BIG thank you again for providing the info which will hopefully get this little plane in the air again. I was blown away when I went to the hobby store and found that COX and this plane were as foreign to these kids as the latest baggy pants fashions are to me! I couldn't believe that they had never heard of this plane or motor! My God had I gotten into a time machine gotten lost? HOLY CRAP, I was flabbergasted that they knew NOTHING about it. I am so sick of all these chains, no mom and pop stores around. There used to be a couple of mom and pop hobby stores that I would frequent for other things like models and such, they are gone! They went out of business when this chain hobby store came into town. Now we have a "McHobby" (joke using McDonalds name) store where the kids working there know NOTHING. What a shame.
