accelerator pump issues

Yea, you should probably get a factory service manual to verify what the settings should be. If nobody has messed with it in the past, just replace the accelerator pump and return the linkage to the same spot. There are three slots for the acc. pump link rod and the link rod has a loop in it that can be adjusted by bending it. The pump should start a fuel stream from the very start of the linkage movement and continue all the way throught the range of the throttle shaft without binding or preventing the throttle from opening up all the way.
