Recently purchased a YS 91 AC to get my feet wet on YS engines. Engine arrived with a bent needle valve, so I ordered a new one from Central Hobbies. I noticed that the changed from buying individual components to a needle assembly that said YS 140 on package ( 1 YSE2740 ). It looks slightly different that the stock one. Am I safe to use it or should I question Central Hobbies? Any help would be appreciated.
