We got them on, got it running, but we are both noobs in the world of duals.
Anygiblet, what are the adjustments that need to be made? We got them on, synced at idle, and seem to have the mixture dialed in as best as we could get using the ol' turn in, then back out method. What's next? Jet sizing? He said that after I left today he up-sized the Idle Jets from 52 to 55 or 57, I forget, per his local VW shop's recommendation.
Oh yes, the issues at hand are backfiring through tailpipe and carbs, mainly at steady partial throttle and decel after holding throttle. Also need any knowledge as to the voodoo of the linkage, like getting them to open in "perfect" sync, as the right one always seems to want to open sooner.
He took it for a trip around the block and said it would go pretty fast if he floored it, and stumble and cough at partial throttle. I say he should be nicer to his bus and not floor it uphill or even test drive it when we already know the carbs are poppin' like so many housing bubbles. But his test drivin' style has always been to floor it through the gears, short shifting and trying to climb 10% grades in fourth, you know, just to put it through its paces...

I hope for Maybelline's sake he didn't drive her like that all the time.
