Carb leaking
good afternoon,
my 01 dyna low rider continues to leak from the carb. Almost to the point where I just feel a new carb might be worth it. As soon as the fuel is supplied to the carb it starts to leak out of the top left hole(see picture). I've had the same problem before however I took the carb apart and cleaned it and changed the fuel valve in the float. Maybe I screwed it up. I don't know. Any help or advice as to what to look for when I pull the carb apart AGAIN. Or should I get a new one. If I get a new one what carb will be fit on here for a good price?

Have you turned off the petcock, run the carb dry, pulled the bowl and checked the little fuel inlet valve for debris in the orifice that fuel is coming into the carb. That little brass valve is raised and lowered by the float. If it isn't sealing tight the gas will keep flowing. Debris and varnish is your enemy.

It could be grit in the port preventing it from seating. The float could need adjusting. Could just need cleaning.

Ok so I pulled the carb off and adjusted the float to 10.5 cm. Put the carb on the bike, with a tank of 3 gallons, fuel is spilling consistently out of the top left hole still. I'm going to take it off again, readjust the float to 11.5cm and make sure everything is clean. If this doesn't work what is the next step? Honestly, I want to throw it in the garbage because I've been dealing with it for over a year.

Have you checked to make sure the float is sealing when it's pushed all the way up? Just take the bowl off of the carb and see if pushing the float up stops the flow of fuel. If it doesn't, then adjusting the float isn't going to help. Probably need a carb rebuild kit.

All the little parts in there are all new. Bought a carb rebuild kit. Gonna open it up again and see it f maybe I missed some dirt or something that would stop it from closing. I'll update in a couple days. I appreciate all the inputs.
