2003 predator fuel leak at carb
I'm not sure what I did but after cleaning the carb I now have a small amount of fuel coming out of the bottom of the fuel bowl where there’s a little drain nipple. This is a Mikuni 42mm BSR. It was fine before I took it apart. I first thought it may be the bowl gasket so I got a new one but did not solve the drip. It seems to be a small leak noticeable after I take it for a short spin. At idle it will not leak or if I rev it, it will not leak.
I looked at the float while the carb is upside down and the float was a little low to being parallel to the carb. The tab that stops the float looks to be plastic and part of the float so I did not know how I could adjust the float. Does this sound like a float issue? I made sure the float and needle was working freely. What the heck did I do?
Thanks.

Probably need to replace the needle and seat. Just because it operates up and down doesn't mean that it's not worn allowing too much fuel or seeping around the o-ring.Plus vibration while running will make it allow even more fuel in the bowl and out the overflow. If you look at the float needle sides and they are shiny,its a sure sign its wearing plus the rubber tip will wear down allowing seepage. A lot of times you can see wear marks in the valve body itself. You can shake the float to see if might be seeping gas in. The old soldered metal floats of the past were bad about this,not so with the plastic ones now days. OPT

Is the needle #37? It doesn't look like the needle. I also do not see a seat.

YEP! I just doesn't show the float needle but its the right part number,it just shows the seat unlike all the other atv breakdowns which shows both PLUS the part # change usually means an improvement in most cases! #3131495 I remember this # very well as a needle valve assy, which has been updated OPT
