Just bought this from a guy in Charlotte NC named Anthony Tran( dont buy from this guy hes a crook ), he claimed was just rebuilt. found no spring in rave valve diaphragm for rear cylinder,
1999, 787 rfi, has 90psi compression front cylinder and 145 psi rear. took apart nothing obvious. Leak down held for an hour. Allegedly new rings. What can cause this condition other than oval sleeve/ cylinder or worn rings.. If leak down holds doesnt that rule out rings and sleeve/cylinder?
are holes in cylinder supposed to face rotary valve side?
