Fast68, I have now solved that problem. I turned the carbs 180 degrees. THey way they were mounted on the X3 intake, they were backwards. It must have been on a boat in its past life. THe fuel was sloshing away from the main jets. After drag week, I made the change, then got out to the track 1 time for testing. It was about 47 degrees, and there was no hook in the track, but there was no bog either. On the 1st test pass I went a new best 60', I think it was a 1.36 or something like that. But it ran out of gas at half track. I should have check it, oops. Then on the next passes, I had tire spin, and my mph was way off. I think my newly remodeled throttle linkage slipped, and I wasn't getting full throttle. I didn't have a helper, so I didn't check that, I didn't think of it till the end anyway.
