Webra Problem

[jivey61 at bellsouth.net]

  Hey guys
 I can't beleive as much as we have had pump problems no one has put a pressure gage on a good running Webra to see exactly what the pump pressure is. I include myself here because I had many problems with my Webra. I only solved my problem with a cline regulater and tank pressure.
If we knew what this pressure was we could compare a poor running engine with a good one. Also this would give you a benchmark to start your setup on a new engine. Just some tho'ts for Webra people.

I see smoke on the ground, but much in the air.  Seem to bog more on the latter half of the tank.  Moved tank to just in front of wing tube to shorten line to pump;but did not see any change.

So I should not need to have is real rich on the high end to handle the up lines.  But still losing power on uplines, so have been richening it.
