jorigger Mon Oct 28, 2013 12:54 pm

Good evening,
i have one problem.
I have buy one vintage kit : Precision Throttle Control CAT n.2450, for the my .049 Cox Medallion.
This kit not fit in the cylinder, the cylinder looks a little 'more' big.
Some people know the reason ?

Thanks

Hi Giuseppe, The original Cox "vintage" exhaust throttle was "mated" to a cylinder with a "ground" outside diameter. Your Medallion has a standard cylinder. You may be able to find a "ground" cylinder on ebay.

Here's photos that show the difference between a "ground" cylinder (on the left) and a "standard" cylinder (on the right) Note the "bare" metal, where the "black" anodizing was ground off, for the sleeve to fit.

Giuseppe, here's (ebay listing-U.S.) a "ground" Cox .049 cylinder/piston, which should fit the throttle kit that you purchased... and your engine.

If you can find a complete throttle-ring/ground-cylinder/piston, in "new" condition... it would be more assured to fit... but this one probably will be fine. If nothing else; you'd have a spare cylinder and piston.

You're Welcome Giuseppe, I sent PM to "Matt" here (member name "exmodelengines") with a short note, directing him to this thread/topic. I'm sure he can get you set-up with an exhaust throttle.
