Rebuilt Tee Dee .049

I rebuilt it with a new out of original Cox package SPI piston/cylinder, carb body, venturi, needle valve and receiver, prop plate, glow head and spinner. The little speck on the NV receiver near the fuel nipple is just a piece of dust. $42.00 shipped.

Joe.
Have you had it running? I would call it a "build" Small Cox Logo

rather than a "rebuild". Sounds like the case and crank are the only original parts.

Nice looking. Now does that new SPI cylinder have quad boost flutes like the old #4 or dual flutes like the new #4(still Cox)? Or is it a Black widow or a Super Bee SPI style. I'm certainly not casting aspersions at all, just curious, as any of those will run fast. If you still have it when I get some spending money, Ill buy it from you. A man can't have too many Tee Dees!

Rod I haven't run it and you're correct about the parts you mentioned. Rusty each side has 3. There is a fat center one with 2 thinner ones on either side.

I guess the next question is, does it have a taper grind? Then it would be about as authentic as anyone needs.

Same as Rusty, pocket money is short at the moment. I don't have an .049 & would sure like one one day, but I do have an original .051 Tee Dee. Haven't run it but it all feels ok. Finding a new piston & cylinder for an .051 would be a little more difficult I'm guessing.

Price lowered.

Was it a old stock OEM cylinder piston or one of Bernies new production efforts?

No. I got the cylinder in a large lot of Cox parts 3 or 4 years ago. It was in a sealed plastic type package.

The thick wall TEEDEEE 049 and 051 cylinders are not tapered, one can easily push the piston almost through it in a new set. I read somewhere that omitting the tapered bore was one of the cost cutting measures COX introduced.

The old-stock thin wall "stepped" ones are tapered. So much so that one of my old-stock 051 after 100+ hours runtime on it still has a pinch at the TDC.

I - unfortunately - could not agree more on the last sentence...with quite a number of TD-s in my inventory I can't stop browsing ebay and it is always hard to dissuade myself from throwing a last-minute bid so as not to win the next one.
