I am after carbs cleaning on my Bonnie 03 because before she could only run with choke on. Now she runs at idle but has some popping, small back fires and from time to time she stalls. I know that the carbs are clean, the fuel filter is clean, the only thing I didn't check was the float height. Could it be causing this problem? I also changed plugs, I tried to adjust the air mixture (now is 2.5 turns) but still the same. Would anybody advise me from what I should start to find the problem? Thanks.
