This is an NOS Carter YS 950 carburator gasket kit. This is for the M38A1 and M170 military carburator with the bent neck. This is the carburator for the 134F overhead valve motor. This is G758 marked. These have been in dry storage for many years. There is a possibility these have shrunk from age and can’t be used, but it is a slim chance. These are sold as is. NOTE: We have been using these and have had good luck with them.
