BTW; Rusty, what
diameter barrels on your TB? Mine are 44 mm, which could be great for
automotive street or racing), where idle transition and throttle response
are more important. For aircraft I do believe that a bit larger would
be better.
Hi Al,
I've measured
mine a number of times, and I recall that they're essentially 1-5/8, which
of course works out to about 41mm. The TWM site only lists
40 and 42 for the 2900 series, so I'm not sure exactly which one I
have. I got it from Atkins originally, with the wrap over manifold, so
I got whatever he was sending
out.
