Tune-Up

The following list of tune-up parts is for Green Diamond engines, but will work, for the most part, for HD engines as well. This parts numbers listing is courtesy of OldIHC (utilizing the IHC MT-52D parts manual Group 6/0603,0604,0604B. Part numbers were then all cross-referenced and matched). As this list was developed by others, you will need to verify the proper part number(s) for your application.

Refer to the Instruction Book / Parts Manual (see Library page) for spark plug and distributor point gap settings for your application.
