Inda spelled it wrong. It's burnish not burMish.
The needle seat sometimes forms a groove from the float needle. To get rid of the groove, you burnish it. Now, mind you, you need to be delicate!!! Use a QTip and some brass polish I think. Others may do it different. Once the seat is smooth, the float needle will seat and the leak may stop.
However, I believe your problem is due to the float adjustment. Personally, I just take the tang and keep tweaking it so the float height is less each time. Sooner or later, it will quit peeing when leaned over on the kickstand. This float height will affect jetting a bit; the fuel must overcome more gravity to get up the jet than a fuller fuel bowl carb would.
Make sense? No? Maybe someone else can explain it better.
Here's Carvr's method, but be careful!!
The Wet-N-Dry Q-Tip Method:
Cut a strip of wet-n-dry sandpaper..the black stuff...a bit less wide than the swab itself. Loop it over the top of the swab, wet with something (alcohol will do..as in 99% isopropyl, not 70% rubbing), insert swab into seat, rotate against seat with light pressure.
The alternating abrasive/swab surfaces burnish and wipe clean the seat.
Start with a piece of 400, finish with 600. Change the strip orientation to the swab to keep fresh grit applied to the seat.
Don't get carried away with it.
