Firstly, sorry for the constant spamming with questions. I seem to be constantly needing information!
I’m on to restoring the AC pump and am getting stickers made. It seems to of been rebuilt at some point, the numbers cast on the side lead to the Tecumseh HG500 (identity plate removed 😔) but the pulley is a different brand - Baruffaldi. Is this normal? Looking at other HG500 it doesn’t have this fitted.
