This makes me giggle!!!!
Tape wet/dry sandpaper to the surface plate, oil it, then patiently push it back and forth longways until you see an even plane of sanded surface. Any gaps or valleys will show up very clearly until it's all uneven. If you're worried about squareness, you can block it on the face of the carb, but I haven't felt the need to do that.Sonreir said:What method do you use for the truing?
