What didn't you like about it?
Is your engine or exhaust modified in any other way?
What steps did you take to dial it in?
I'm trying to figure out why this mod works for some of us, and not for others. I've got a theory.
Oh, and if your price includes shipping (to NorCal), I'll buy your setup... if you don't want to try it again, that is.
Also, if you need a no-frills carb that runs well, I've got a $26 ebay carb that came on my TW, which you can have. It's much less finicky than the pumper, and very reliable.
