Hi all, have this Ozito chainsaw, which is probably sold under many different brand names, and I have seen many saws with this same carby, so someone may be able to assist. I have four brand new carbs that I have tried, all the same result. I cannot get the primer bulb to pull fuel through the carb to prime. The primer bulb, all fuel lines are new, the fuel tank strainer pickup is clean. I can draw fuel by suction from the tank, but not with the bulb. The carbs are off ebay from China, but I have seen them used on saws before, and they are ok. Just this saw I cannot get right. The carb has a line fitting on the top, which I think would be the pump, and the fitting on the side would be the return, but trying all sorts of plumbing has failed to get the carb primed. I have posted the pic of the carb as it may help to confirm my ideas for the lines. I have tried the line from the tank direct to the top fitting, and the suction nipple on the bulb to the carb side fitting, and the output from the bulb direct return to the tank, but no go. Any help would be great. Many thanks.
