Pulled the carbs last night and lo and behold...dropped the #4 bowl and the main jet and well were laying in the bowl. Who knows how it worked its way loose as these carbs have never been apart. I checked the other 3 and blew everything out. Haven't put it back together yet (ran out of beer), but hope that was it. I only had one carb bowl O-ring, so I put it on the worst looking one. Honda gets $35 PER carb gasket set, sheeesh! Any other sourse for bowl rubber parts in case these end up leaking???? The NAPCO kits you always see on ebay for $15 are for the 81-up CV carbs.
