Wow, thanks, of course this is now another operation I will have to perform ... again... but I have to put my screw-on adapter for the oil filter in place this weekend so while i'm in there! I really have to get back to my project about cataloging our posts- there is way too much information on the site not to. I will manufacture something and get that connection air tight. I also purchased one of those "digital"? carb-mates, so.. timing, carb tuning, balance tube manufacture, upper front cover sealing and ... I will do my best to document the carb process, my goal is to be just happy with the power output and have a smooth idle. (and no oil dribbles)
