Tried to start the engine again today and I think I may be on the right track now. I noticed that after the engine would start and run for less than a minute it would stall if I reved it, and in that situation the float pin stayed down for quite a few seconds until the bowl filled again. Ie: it ran out of gas due to restricted fuel supply. I took the plug out of the bottom of the carb and with the tank valve open I was only getting a steady dribble rather than a gush of gas. I assumed the filter in the tank was clogged because I hadn’t removed it before now. Surprisingly after I took it out it looked fairly clean to me. I think I read somewhere that these can look clean and still be clogged. I sprayed it with carb cleaner and blew it out with compressed air. Not sure of other ideas, but it sure seemed like I had restricted fuel flow before. It seems pretty clear now when held up to the light (picture below)?
What sort of sealant (Teflon tape okay?) should I use to put the valve back in the tank?
