Hay KeithB . I bet you thought the Webra thread was dead . I have a new one I am trying to get to run well. I have about 30 flights on it. I have a Bolly 140 pipe on it at 24 In. to the 1 st baffle and 30 inches overall length. I have a good idle and ok transition most of the time my problem is it seems to want to lean out on up lines and I cant open the main needle enough to change this without messing up other things. I have read your input on the pump and would like to know if I should Increase or Decrease settings or maby not change them at all ? it I seemes to me that I need more fuel on the big pulls and vertical lines but I may not understand the pump as it relates to high speed needle setting. BTW the main needle is only a turn out. I will be in pretty good shape if I can fix the vertical problems . Any advbise would be great. Oh yea Pro mix 2 carb.
Thanks Kirk
