Thanks Jim, this was my uncles so I’m not sure how old it is? It has, “7M” stamped on the front of the carb and I haven’t been able, yet, to find parts and “O” rings yet. I’m sure they’re out there, I just haven’t hit the right spot yet. I’m very familiar with the antifreeze treatment. We learned that in the 80’s. I was always buying somebody’s throwaway and rebuilding them. I have an OS 120 with the Hemi, Saito style valve arrangement I’m rebuilding. I’ve never seen one so this is a pretty neat thing for me. I have two of the Enya 90, 4 strokes from when AMA changed the engine size rules for pattern in 1983. These things are powerhouses!!

thanks again and I’ll keep you posted, Bill
