Hi. Long shot but I think I may be onto something. Opened and cleaned the carbs again, changed plugs and generally cleaned stuff. Got everything together earlier and guess what, the left side is dead (the right side was dead).... Again I checked plugs and fire, all fine. I then got a brainwave and opened the bottom drain bolt, and only a few drops of fuel came out!!! Both carbs were almost completely dry. I tried blowing air into the intake and couldn't. I realized it could only be the floats. Removed the carb, opened the bottom and saw that the float valve was stucked. Removing it, I can clearly see some dents and scratches (here and there rough edges). The other side more or less looks the same. I'm pretty sure that this may cause this one side then the other side "dead" story, sticky float valves. Do you think a would still be able to get spares e.g. float valves and seats? Lastly, do you adjust the float levels?
