Ya it's been balanced a couple of times..


With the 34#'s it was running about 90% Duty Cycle at WOT..I have a Walbro 255 in it. There is very little difference between this build and the previous one so the Tune was easy to adjust..we just fattened up the Fuel Curve a hair for the 6ci difference.
Post pics of yours Chris when you get it back today.
