Outdoor Power Equipment and Small Engines - Buying Engine Rebuild Parts; What's Best?

I have three small Honda engines to rebuild (5.5. and 6.5 HP). I’m asking for information on parts that work. A company I found on line, The Mowerzone, has parts for Honda made by Yamakoyo that are substantially less expensive than actual Honda parts. They say on their WEB site,

“All Yamakoyo parts are guaranteed to meet or exceed the standards for the OEM part they were designed to replace”

Has anyone here had any experience with these parts?

Thank you,
Jim

I can not vouch for any particular maker, however with prices of some OEM parts in particular Honda, John deere....on parts that are obviously simple and inexpensive to produce, I personally have no problem using them. After market parts are sold by several companies or at least distributors of aftermarket parts. Try also Oregon parts and Bently.
