I am trying to set up a VP-20 on a .91 Saito. The pump is mounted between the motor mounts on the firewall. This pump was given to me used and works, but is out of adjustment. When I tried to run the engine, I couldn't open the high speed needle enough to make the rpm's sag. It's a real pain to get to the pump for adjustment. ( Engine has to be removed. )
If someone has a pump with the factory setting handy, and a feeler guage, I would sure appreciate the measurement from between the inside of the hex-head plug, and the edge of the boss the plug screws into. Or if someone is running one on a .91 Saito, this same dimension would sure be a help. Thanks, Tim
