I finally decided to try my electric starter and the engine started, but it wouldn't run. I backed out the needle valves and it still didn't run. I finally got it to run by holding my finger over air intake, choking the engine. I think i have an air leak and that is causing the pump not to work on the carb. I have a stupid question, but since I got the saw in pieces I never saw which tube on the carb is the feed tube and which is the vent tube? Can anyone tell me? Right now I have the feed line hooked to the smaller tube located in the middle of the carb and the vent line to the larger tube that is closer to the top of the carb. Is that correct? Any help is appreciated. Thanks
