Attention vintage riders, I am working on a 1972 AC Panther 440 with a walbro carb. First I was not getting any fuel so I rebuilt the carb. Now I am getting to much fuel that it always floods out. I got both needles adjusted where they should be but no luck. Any suggestions ? Thanks

toss it- put on a mikuni 32mm and follow the jetting specs from one from the late 80's, same motor, change fuel pump, throttle and choke cables. No more problems and completely tunable. If you are going for all original, good luck. Those carbs were unreliable back when they were new. Thats why we all carried 20 plugs and were happy if we got 20 miles without a breakdown!

Did you replace the valve seats? If you didn't go replace them.... then....Throw the specs away on the float and go back and re-adjust until you don't get flooding...there is nothing wrong with that carb as these were on a bunch of machines before Mikuni but they ALWAYS had the floats set too high just in case you did huge long full throttle runs which could wipe the bowls clean. Once you get the floats set correctly that motor will run fine on that carb. Just be sure you didn't accidentally clean a jet out too big.
If you want all original don't do the Mikuni.
