I have scoured the forums and there is still a gap in my understanding. I hope someone can clarify it for me. The symptom is the fuel dripping out of the overflow. I measured the fuel levels and found the offending carb had a fuel level that was at about 30 mm above datum. Sure enough, that was also the carb that was overflowing.
So I removed the carbs, opened the float chamber, bent the tab a hair or two, reassembled, started her up and viola! Absolutely no difference. So I have the carbs off again and this time a cleaned out the valve. I hope that it was just dirt in there, but i will never know since I blasted it with an air can.
My question: Is there a way to measure the correct float position with the carb open and dry? I cannot believe that it is a matter of trial and error with a full reassembly in between each trial. I searched the forums and my manual but I cannot find specifics on this step, if it exists. Help! I have attached an image of the open float chamber and the float tab resting on the valve by gravity.
One more simple question. My spark plugs are always black and oily instead of dry and that light tan colour. To me this is the mixture adjustment but a cannot locate a spring-loaded mixture screw that is attached to the carb body. Can someone please point it out.
Thanks for your help.
