Hi everyone I,am a little confused with my motor. I was told my mac was a mc5 when I bought it off ebay, but not completely sure. The block says mc5 but reading the forums. it seems the sparkplug is on the exhaust side on a mc5 and mine is on the other side. Could a different head be fitted on a mc5? Also does it look like I have the large rings?I know alot of you know a whole lot more about these motors than I do. thanks for the help Mel
