Runup would give me full static on either pump. I take off on both. Some time later in the flight here's what happens: I'm be running on left pump only I increase throttle to climb mixture goes off the scale lean engine falters I switch on the right pump (which feeds from a separate tank), mixture comes back up and 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. They were very restrictive, especially the left one. After I clean them with high pressure air they flow much better, but I'm beginning to think these filters are not good for our purpose. They're too small and too easily blocked. Additionally there's no nut on the center section so they're hard to get apart at both ends. I think I'll get larger canister type filters with a drain like Buly's. Buly - where did you get those? Got a part number? Anyone else have a filter part number they can suggest?
