I've = been having fuel flow problems on one side for a = while.

Runup would give me full static = on either pump. I take off on both.

Some = time later in the flight here's what = happens:

=A0=A0=A0= I'm be running on left pump only

=A0=A0=A0 I increase throttle=A0to= climb

=A0=A0=A0 mixture goes off the = scale lean

=A0=A0=A0= engine=A0falters

=A0=A0=A0= I switch on the right pump (which feeds from a separate tank), = mixture comes back up=A0and engine runs = normally.

I have the small Earl's in-line = filters with the conical (brass?) filter blocks. They always = "look" clean when I take them apart, but yesterday I tried blowing = through them.

I think I'll get larger canister = type filters with a=A0drain like Buly's. Buly - where did you get = those? Got a part number?

Anyone else have a filter part number they can = suggest?
