Anyone got a picture of an exploded view of any of these .049 COX engines?

Appreciate your help.

Here you go. What cha looking for?..............John

If you're planning on working on your engine, pay particular attention to the venturi gasket (Part #1300 between the tank and backplate in John's view). They are small and can be easily damaged or lost -- probably more aggrevation can be attributed to this part than almost any other. Also be sure the reed is free, clean and does not have any creases. Be easy handed -- the parts are small and can be mangled if not careful.

A visit to the [link=http://www.coxmodels.com/prodinfo.asp?number=C01300]parts department [/link] at [link=http://www.coxmodels.com]COX models [/link] will give you a source of parts and additional exploded views.

Enjoy your engine.

vauxhall,

Thanks ! exactly what I was looking for.

Andrew,

About the venturi gasket... I realized that it was warn out... thanks for the tip.

I replace old O rings (the gasket mentioned above) with slices of standard sized silicone fuel tube. It works beautifully and saves having to buy a complete parts kit for one small part. The only problem is slicing them straight.

Razor blade, the other sharp surface...

My eyesight needs to be sharp too, I think that's the problem.

I read on a post on the 1/2a forum here a while back about a guy who slides the tubing onto a skewer. Rolling the skewer on a flat surface while holding the blade against it produces a square cut. I've never made one of these little gaskets myself, but I need one. What size tubing should I use? How thick does the gasket need to be?

Wayne,

nice tip re the skewer.

I make them slightly less than twice as long as the originals but not longer than the spigot they go over, the length is a guess. You should be able to feel the resistance when you put the tank together, that way the "grommet" doesn't have to be truly square to get a good seal.

I make them from standard sized silicone fuel tube, the size that fits all the 09 to 60 size motors I use. Damned if I know the size, I just call it standard fuel tube.

Actually, that was pretty vague of me. Try for one sixteenth of an inch long. That should be ample length if it's cut square.



Luke.

Thanks for the information. I may try making one later today.

You don't have to buy a rebuilt kit to get one thing. call them and tell them what you want.
i just bought a dozen o rings, tank caskets, head shims, fuel lines and springs 2 weeks ago.
it was better than trying to cut them.
Have a good day
