I got my bike running and up to bench sync. My bike shows signs of being a mixed bike; it seems to have some CB750F parts though most of the parts and the serial number are CB750c. I know that the person who sold it to me built it from spare bikes he owned. I have also found some but not major damage work (stripping and cracking) from someone working on it or making marginal parts fit. My carb is a VB42A.
My question has to do with the bike being a "Frankenstein" build. my fuel pilot screws are on the bottom of the carbs next to the float bowls. The fuel pilot screw my third carb is what looks like a brass cap screw. The other three screws on the other three carbs are a unique screw style screw head. They have a flat head driver fitting and a "wing" which sticks out and stops on a flange on the float bowl. (confusing to just describe). I am wondering if the odd cap screw on the third carb is a set screw, not to be changed, for syncing the fuel adjustment on the other three carbs to its fixed setting, and if so why isn't it on the number two carb like all the other set adjustments? Or is this just a screw that the guy who built the bike had around and used to replace the unique style head?
Why is this site rejecting my JPEG files!? well no pics I guess
Thank you for your time
