Looks just like any Rossi .40, and it is not old..at least the carb is the new style.

A pic from the Rossi website



Yours has the older style muffler.

I find it amazing that you can get 25.500 out of a front intake, side exhaust engine with such a small bore carb and a stock un-tuned muffler. Every other Rossi .40 on the planet would have to run with nothing but the spinner to get those numbers..and it would have to be a smaller spinner than the one you are running at that.

Which brings on an even more incredible feat. That you are able to run a plastic spinner at 25,500 and not grenade it. Of course I would like to point out that your plastic spinner is more than likely the only plastic spinner in history that has not flown apart at 25,500, but then you probably knew that.

An interesting side note..your tip speed is about 758 mph.

At STP this is roughly .99 Mach.

You guys up in Canada are sure getting a LOT better engines
than we are down here!

I also see in your pics that you have it in the garage..under lights.
