Not Ranked
John, I think the number was 384 but did not get a printout and you know how it is with old age!! Very lean condition, above 15, thru entire test. Drew had his wife bring up the community jet box and with Gary Sharapata's hands and some of Matt and Drew's tools we changed the primary jet to 78 and secondary to 82. Power valve was a 6.5 and was in good shape. Did not have time to pull a third time as they were getting backed up and I wanted everyone to get their chance. The car was totally different on the way home!!! Ran like it had a different motor in it. Funny how much a little change can effect the performance! I am really anxious to get it back on the dyno and see how much improvement there is, both hp and a/f ratio.Thanks to all who helped and to Kieth for the jetting suggestions. A special thanks to Jay for not having the guts to go over 4000rpm on the second pull. With the lean condition it probably saved me some parts!!!! Just kidding on the Guts thing spineless, I mean Jay.
