well i found out this afternoon why i couldn't ever permanently get the gas to stop leaking on my to-20 at the carb where the secret screen elbow screws into it. pulled it out to inspect it closely, and noticed the inlet hole was cracked. it's had to have been this way for a long time as i never could get the leak to stop for any length of time, and it's been getting worse. anyway, started digging around to see how badly it was actually cracked and found out it was pretty bad because a whole chuck came loose and fell off it. my questions are, has this ever happened to any of you? if so, did you find a way to fix it or did you replace the carb. if you replaced the carb, did you have to replace the whole thing or can i obtain the top half of the carb separately from the bowl half? i'm fairly sure this is the original carb, and would like to keep it if possible. i was thinking of trying to braise it, but thought i'd run it past you guys first. (i've learned to ask first, then do) i'll appreciate any help or advice... -mike
