My recently rebuilt 235 is running great, but I have a funny high pitched
noise at 40-50 mph. The faster I go the louder it gets, and when I let off
the gas it stops. If I slow down to 35 or so it stops. It' a fast,
pulsating (not constant) sound, and I don't think it's the fan belt. Oil
pressure is high, and nothing happens with the power or anything, just this
irritating high pitched noise. Sounds like a bunch of birds chipring. Any
thoughts?
Thanks!
