I know some have seen this , but it may help others if you know a good machinist . I got this Honda 160 with a DB-30 purchase , well it didn't have a clutch on it ? Yep pressure washer engine , tapered shaft and no key-way . My Buddy chucked the whole engine in lathe ( removed spark plug ) and turned down the shaft easily and also cut the key-way too , best part no engine tear down and he did it for free , I guess he thought it was a challenge !
