Seems unlikely to me. IMO it's more likely that the worn shafts (and
bushings/housings) are letting the throttle plates drag on the bottom of the
bore, blocking the throttle from closing fully when it returns slowly.
"Goosing" the pedal is like slamming a door that sticks.
Sorry, not much help with the other problems. I saturated the fiberboard air
deflector (on my former TR3A) with rattle-can paint (which took a lot more
coats than I thought it would, 6 or 7 as I recall) and it seemed to hold up
well. But I don't drive in the rain much, so doesn't prove anything.
I've seen several people fashion replacements from thin aluminum, but of course
that doesn't look original (though it does look nice).
