I have an old inherited Miller bluestar 2e welder that was handed down to me. I am needing a part off the pto side of the motor. This is an old unit. The round circle plate that is bolted to the oil pan that is pressed on the crankshaft. I am probably S.O.L. but this is worth a try. Other than the serial number off the unit ( ja369806 ) I have no other numbers. It has a Tecumseh engine ( 10 hp I believe ). Can someone please direct me to a part number or someone that can help me locate this plate ?

ANy response will be appreciated>
