Head and valve covers all checked. Decided to use 1980-1981 ATC185 / ATC200. People most of time don't ever really open them up or build up pull start motors. Now I can get a manual decompression for a kick start 200x. I'll clean it a bit more but I removed all gaskets, chased all threaded holes. Scotch brited all surfaces. Still think underside of Head should be fly cut to clean up surface maybe. 002-.005". Head guy can decide. Needs new seals, seats prob need recut after atleast 21 years. It could be as old as 37. I trust nothing. Valves should be fine after recutting. I have 1 more day left to mess with it. I spend 2.5 hour tonight from checking to ready til now. Prob need another 15 mins and I'll call it a day. It's a total disassembly job next.
