1st Issue: Check your fuel pump. It may be delivering enough fuel for
regular traffic, but not quite enough to keep up with 3500 RPM. As the
float bowls empty, the mixture will lean out. It's possible I suppose
that it leans out just to the point that the fuel pump can just barely
keep up, but not catch up.
2nd Issue: Check the seals under the washer pump jets and the
windshield wipers.
HTH!
