I have 5 atc70's, 3 are 83's and 2 are 85's! I am doing 125 swaps on he 85's because they have the best frames yet the worst engines. So heres my question, has anyone ever swapped out the 1984 below manual cam chain adjuster for the 85 auto adjuster? I have pilled both engines down and looked at the cases and they seem identical. I know the auto uses oil pressure [;is spring but I cannot find the oil galley in either case, the 83 or 85. I am beginning to think its in the bolt hole for the jam nut. Has anyone ever done this and does the 83 have the oil galley like the 85???? If no one knows I guess I will figure it out soon enough. Thanks guys
