darn .049 motors how do you
how do you get the glow head off the newer 2 slot motors the whole piston sleeve comes off all the time!!! and there is not flat spot on the sleeve so how do you get it tight on the block?
I know the old ones have a flat spot you can use the wrenches on?
THANKS

The two top fins on the cylinder should have milled flats. The wide slot in one of the factory wrenches fits these flats. Some of the older wide exhaust motors had this too.

Some of the newer cylinders don't have flats. If this is the case wrap the cylinder in leather, an old belt is perfect. Use a pair of Chanel locks on the LEATHER. CAREFULLY hold the cylinder this way while you use the Cox wrench on the glow head.

You can wedge it between 2 pieces of carved wood in a vice. Heating up the cylinder might help.

How new are these cylinders?
I remember years ago when Cox tried the screen over the exhaust, then the narrow slits...both reportedly for preventing or lessening the possibility of grass fires, removing the cylinder was apparently an oversight. You could not use the normal wrench in the exhaust, and no flats on top. Don't know how many were made that way.

Re: darn .049 motors how do you
Such a fire from injecting fuel through a cylinder with a lit glow plug can occur. Happened to me once, happily only the gravel was burning, very briefly. I quite plainly over-primed the engine.
