Scratched float valve seats?

I read in an earlier thread about over zealous cleaning can cause scratches float seats and flooding. I am expierencing this flooding was getting ready to pull carbs back off to check if i did something wrong. If i did scratch them is their a way to repair them or will the bodies have to be replaced. If replacement is the case i will prob not keep the bike due to knocking noise coming from under stator cover " not upper cam chain already have manual adjusters" . Any help will be greatly appreciated.

so youre complaining of a knock.. and flooding... have you thought that the two could be related.. a dead cylinder = knock = unburnt fuel... do you have spark on the front cylinder

I do have spark on both cyl the knock is only on deceleration or coasting it goes away on acceleration and gets worse the longer i ride. The problem I am having after cleaning my carbs and replacing the float valves. is after a half hour or so of "spirited" riding i was pulling into my wifes place of business and the bike just shut off. i had to jump start the bike and when i did white smoke poured from the exhaust.and smelled of fuel battert tests fine and stator is putting out 13.3 v at 2500 rpm. so other than flooding i am lost.

I was the one that posted about the scratched seats ,if you did not use a very abrasive sandpaper or a scraper to clean the seats I would not worry.as for the knocking behind the stator cover it could be balancer bushings and I heard one member on here that had trouble with the rotor on his stator,keyway issues I think .Lance should chime in on this, or PM him he can give you a better Idea about the knock.I think snap on makes a tool that you can use to resurface the seats ,but I replaced the carb center assy section on the one I was working on. That is what the owner asked for,I am not sure if the seats are removable,are you sure you have the floats set correctly?

I set the floats with the line on the body. i am coastered but not shaved. I am currently running a 45 idle jet and a 150 main with hollowed out stock exhaust and this has worked for the last three years. I am just trying to figure out what I did wrong will be pulling carbs back off tonight or tomorrow to check them. As far as plugs go i am running the ngk irridiums recommended by several people on the site here.
