Gdads51 traced the motor down to a 72 pontiac. I ask for parts for a 72 firebird with a 250 inline.lol. So far so good. I was all hung up on wanting to find an exact rubber coated brass copper replacement. Ended up buying the only thing that was the thickness and diameter. Wasn’t brass or rubber. lol. I appreciate the offer on the carb. I’m gonna try and get this one going. Definitely don’t want that fire though.
