Help me settle an argument

Results!!!!! Well, not really.

It runs exactly the same as it did before. :banghead:

Yup, no change whatsoever. Exact same 60 ft, 330 ft, 1/8 mile, and 1/8 mph as before. It ran lean at first but once I jetted it up it was in the 12.8-13.0 afr range, which was where it seemed to run best with the 650 main body. I wound up running a whole string of low 7.80's at 86 mph, which is exactly what it was running last week. Maybe I could have played with the jetting some more but I don't think there was a tenth or more in there.

I also tried a couple other things, like taking out the 1/2 open spacer between the carb and intake, running with and without the air cleaner, and manually shifting instead of auto. There was no noticeable change with or without the spacer, adding the air cleaner slowed it down, and manually shifting it did the best mph of the night at 87. Like a dummy I forgot my timing light, but I don't know if that would have made a difference. Would the required timing even change with a bigger carb?

Well that's it, I was hoping to come back with good news but it didn't work out that way. I'm kinda bummed out about it, but that's the way it goes sometimes.........................
