rebuilt my stock '72 38's - and reinstalled them and they ran great.
then I let it sit for about a week, got ready to crank it again and noticed they were leaking/overflowing like crazy. So I poked around a bit and noticed that I hadn't reinstalled the small plastic pipe that connects the two carbs (there's a large and small connector tube). gas was pouring out of that small pipes nipple - then once I added the small tube...it filled up the other carb.
I pulled them off again and pulled the bowls and noticed that one of the floats had a leak and had a little gas in it. so I ordered and installed new floats in each carb.
reinstalled them. cranked it and it ran great. road around for about 20 miles worth. Accidentally had been running on RES and managed to run out of gas (not far from a station). put another gallon in and road about a mile and half and when I stopped, I noticed the same right carb was overflowing exactly the same!!!. flowing so much that it was soaking into the airfilters.
Road home as quick as I could (about a mile or so) and when I got home it wasn't leaking anymore? (I can slosh the tank around an hear 'some' gas in there so I dont think its empty again....just isn't overflowing anymore (yet).
so my guess is leaky new float (unlikely - but possible), randomly stuck float, needle not seating randomly?
still need to pull the carbs again but not sure what to look for once I do (other than a leaking float).
what do you guys think? and what should I look for?
btw, tank is recently lined, carbs just rebuilt, new petcocks, etc,etc so I'm doubtful that its trash. only have about 40 miles on everything since replacing/rebuilding all on those things.
