Don't bother checking the tach. I = have a prop=20 tach and it says the engine tach is correct - sorry 'bout that. = But, it=20 was a 60F day so the denser air help - there! feel better {:>)? = My prop=20 is 74 x 88, beginning to wonder if I should have left it at 76 (the = devil made=20 me say that Rusty).

Actually, I would rather make an entire = intake=20 manifold that build another fiberglass duct {:>).

" I've measured=20 mine a number of times, and I recall that they're essentially 1-5/8, = which=20 of course works out to about 41mm. The TWM site only = lists 40=20 and 42 for the 2900 series, so I'm not sure exactly which one I = have. "

OK, in the above quote, what I meant was- = they don't=20 list a 41mm, only a 40mm and a 42mm. For the record, = I know=20 they make larger sizes (so quit telling me <g>). =20
