7 1/4 Posi??????

Someone on Facebook Marketplace sold me an SG 7-1/4. I paid to have it shipped. He turned one wheel and the other turned in the same direction. I paid to have it shipped. when I received it, it was not an SG. the gears were rusted stuck. I was out $600 after shipping. I didn't blame him. So, testing it as described in post #2 is a MUST. I did eventually buy one here on FABO. replaced the seals and bearings, checked clearances and it has been working fine. [I don't do hole-shots with my 273]
