Number Three Carb seems to be a little ****ed

[Guest]

I finished repairing my turn signal problem this evening, and noticed a small wet spot under the bike. It was gas. I looked around and didn't see anything leaking. I started the bike and let it idle, and after a while it piddled a squirt of gas out of the #3 bowl vent tube. I started timing it and about every 15 to 18 seconds it would do it again. Does this sound like fuel is leaking down the vacuum tube from the petcock? I have A NOS '80 tank with it's dreaded petcock, both less than a year old.

Could be just the float sticking from sitting for a bit. Wack it with something and see if that fixes it. No really, just wack it.

Float heigth or bad o-ring in the float seat.

Float height was set just the other day before I dropped the needles. I'm going to try running it on prime with the vacuum blocked to see if that changes anything before I take the carbs off again. The float seat O-rings were the only thing I did not check. These carbs were initially rebuilt by Wired George before I put the DJ stage 3 jet kit in it. Three floats were off, a rough burr on the fourth slide and the wrong O-rings on the Pilot fuel screws (too large) along with the strange lean jetting. I guess I shouldn't have trusted him to do anything right, except take my money.

Seems that I don't need to get the old girl depends, but I might need another petcock. Running on prime there is no problem. I didn't have time to check it in regular vacuum mode. I was going to drive the car this morning but my Son had not closed the trunk all the way and the 8 was as dead as a door nail. I couldn't get it to run trying to block the vacuum port, so I left it on the petcock. Apparently the vacuum port is blocked in the Prime position. I'll check it this evening both ways. Hope I don't have Gremlins.
