pre 1975 049 cox engines

I assume these are old engines that have sat quite a while. I also assume they rotate and have compression.

You need to take the engines partly apart. Don't mess with getting the crank out without a reason to, an overnight soak in alcohol will clean inside if needed. You want to test the head on a glow ignitor to make sure it is good. The tank is gonna need cleaned with denatured alcohol and a toothbrush. There are gaskets and fuel pickup line that needs replaced.

You are best off to buy gaskets and reed in a kit for re-assembly, but you can reuse a good crankcase gasket, and make a venturi gasket from a ring cut from fuel line, with silicone for a pickup to get flying quick.

Don't forget to remove the needle and blow alcohol through with a fuel ball or syringe and gently wipe the needle clean.

Hello,

Welcome! Don't trash em....... Your best bet would be place the mess on a piece of white cloth take a picture and post it on here and we can sort the mess out.

A lot of parts are interchangeable and assembly is a snap! It's probably not as bad as you think.

Trashing any of what you have could be exactly like throwing money away;if you want to fly you need wings (planes)and engines right?
we can get you something going out of what you have I bet

Most of the time I find that the fuel pick-up on the back plate has gummed up dried out fuel in it. Take a 1/64" drill bit and run it through the nipple with your fingers to clear it out. Works like a top. Then blow it out with an air gun. You can pick up replacement parts from these links.

Some people don't like this guy, but he has some parts that the other 2 do not.

Brake parts cleaner with the straw on the can clears out gummy orifices very quickly too. Don't forget to put on your safety glasses, because it always comes back atcha.

Welcome to CEF, Getback.

It's a time-honored practice to NEVER toss a part until you have a suitable replacement IN HAND. (emphasis added)

Well said SD!

I think it only fitting to add those upon occasion.

Super Dave
Do we have to pay for these?

Duke:

No. I enjoy "dispensing the TW's for free and when I feel like it.

They will be published post-humously for an astronomical charge. I'm authographing copies now. Revenues generated will be sufficient to put our five grandchildren though Harvard Law School.

Thanx, Mark I've been frolicking on a history forum but drop in here to see what's happenin'.
