Thanks for the link.. I'll give them a shot. BTY, based upon the cowl I've narrowed the engine down to: 200TX, 200CX, 225T, 225P.

Which brings me to an interesting question. If the engine is a 200, and it's got 225 carbs on it, does that change the HP of the engine?

Specifically, what I'm thinking is that since the venturi of the 225 carbs is wider than the 200 carbs the airflow thru the venturi is going to be less. What I mean is that if the engine is in fact a 200 then it will require x amount of air to run. By making the venturi larger with the 225 carbs the engine will draw the same amount of air in, (because that's controlled by the engine's displacement), but the air velocity through the venturi area will be different, due to the larger opening. The engine will be able to breath easier, which may be a good thing, but will the engine still have enough vacuum to properly break up the fuel from the main jet as it enters the air stream in the venturi?
Damn, my head is swimming now... <sigh> You shouldn't do this to an engineer... it's bad for our sanity....
