compression ranges between 188 and 196. found very minor leaks at rear of intake, bottom and top of adapter on rear carb. assuming all 3 (all at rear) is enough to matter. intake and head looked good so I cleaned it up and installed a new gasket. old one had a small ding near the leak, probably happened during install. adapters are very crude. sanded tops and bottoms of both along with the carbs. I was surprised how poorly they were made. maybe reassemble tonight, tomorrow maybe.
