Webra Problems

 This trash was a piece of plastic that couldn't have come through the YS filter. It was  the size of a pencil point and whitish in color. To pull yours apart is up to you. I believe I would run it and watch very carefully for rpm sags at high throttle.

Do you think the trash in the pump was there from manufacturing?? I have a 145 not yet run, and I am wondering if I should pull it apart first before i run it for the 1st time.  Lee Davis has certainly emphasized the need to ensure no foreign crud get it from the fuel system, but I hadn't thought about manufacturing tailings.

I just checked my backplate on my Webra 145 and there is a half moon track on the top of the skirt relief on the backplate. My engine has been ran just like Brians, lean, while I was trying to set it up. My sags came from trash in the pump, that was there from day 1.
I used a YS filter, Cool Power 15%,17x12 @8000 with pipe set per Lee's suggestion. I also wasted 3 contests on this problem. I have 60+ flights on the beast. (civil word). My cylinder, piston show signs of excessive heat, also. If this thing gets rebuilt it will be over the winter months. I have a cline regulator and plain B/P with a pressure tap on it now. It seemed to be better on adjustments on the ground, but since the markings on the B/P, I won't even continue, 'till I rebuild it. Let's see 60+ flights @ $550 =$9.17/flt + fuel.
I know how you feel Brian. I now have my reliable YS 140L in my plane.

See you-uns at the Nats
