I had a new pilot jet in my toolbox and put that in and fitted the carb on the bike and started her up, she wasn't running right, so took the plugs out and turned the bike over and the good cylinder was blowing out fuel and the one which was giving trouble had nothing coming out. I checked the float bowls and the left one which has been giving me trouble was nearly half of the right side, so carbs out again and bowls off and checked the float valves on both and looked ok. I put the carb back together and before fitting back on the bike filled the carb with fuel and then drained each bowl and both were the same level of fuel. So hopefully when I get time in the week, I can checked the plug out method to see if fuel is coming into the cylinder.
I have had these carbs off the bike so many times now, it is starting to get frustrating.
What I can't workout is why the float bowls would be different levels as the pressure of the fuel coming in pushes the valves down to fill the float bowl and when full, the floats push the valve up to the hole where the fuel is coming in. The floats feel nice and free, so can't see them getting stuck.
Any help would be much appreciated.
