need help with 1981 440 ltd carbs

[backontheroad]

hey guys i got a 1981 440 ltd it was running fine but dripping a drop or 2 out of the overflow line on the right carb i took it off to check to see if the float wasnt going up high enough or if there was trash in it i adjusted the float hight not by the book but buy bending the tounge on the metal float lever some with a screwdriver put it all back to gether and now it runs rougher than before at low speeds once i get going its fine its prone to cut off now and wants to sputter when starting out choking it just a little seems to help the problem did i bend the float valve to far ? or is there something else i could check it also when i am going down the road if i let off the gas it let the engine slow the bike down it apears to backfire slightly i had to idle it up with the little black knob in the center of the 2 carbs to keep it running after i put it back together i didnt go into the carbs just pulled the bowl on one carb ( the one that was leaking) and messed with float height i am pretty sure i got the throttle cable back where it was before as i marked the threaded end and ideas would be greatly apreciated also this did not stop the dripping but when i pushed up on the float and blew air into the line it was closing off any ideas ?

You already have a thread opened on this problem. It's not a good idea to start a new one where the other one left off or you will end up getting the same suggestions that have already been covered once.

Adjusting the float height needs to be done by the book if you don't know how to do it, not by best guess. You could wear the screws out taking that thing apart trying to "guess" at it and never get it right. Yes you probably adjusted it too far. You can press with your finger a lot harder than the amount of pressure applied by the float so the fact that it closes that way doesn't mean the valve is good. Another possibility is if your float bowl has a brass tube sticking up out of the bottom for the overflow check to make sure there are no cracks down the side of that tube.

thansk for your response sorry bout the double thread posting ill check that tube the running bad was because i put the air box back on wrong and guess it was getting to much air it runs much better now but still drips gas so ill check the tube and see if it has a leak or crack in it and thanks again so much for your help
