You are very correct - forget cheap amazon parts - buy as many OEM Honda ATC parts as possible. eBay is your friend. the 200S was made from 1984 - 1986 - all parts are interchangable. For your pull start - 1981-1983 ATC185S will also work. Keep in mind with pull starts - later models had an automatic decompression set up that are cumbersome to rebuild and hard to find parts for - they are NOT needed to work.
