This is on an XR400, but I'm posting here because there seems to be a lot more Edelbrock info than the 400 forum. I've had the E carb for a year and switched it to a different bike. My question is all about the pump, I know how to adjust the needle. Is there a baseline pump adjustment? Like so many turns out? When I installed it on the first bike I went 1/2 turn out from factory setting, and it seemed to work ok/good. On next bike I ended up 3/4 more turn out to get it to snap instead of bog. Maybe I should have done that before? So now I want to know where I'm at and record it. Can I bottom it out and count the turns out like a fuel screw?
