This could be a hole in the fuel line or plugged tank vent or carb needs rebuilding


A week is like a half of a year for me these days!
This thing is pretty new. The fuel line looks good with no tell tale leaking. It does the same thing with the fuel tank cap loosened, so the tank vent shouldn't be the problem. If there are no substantial improvements soon, my next thing will be the carb kit.

An interesting thing developed recently. We were desperate for a second saw, so I pumped the primer bulb HARD 20 times or more, wondering if I/that might dislodge or free up something in there, or show a leak somewhere (no leaking). After starting it I was able to rev it up to the high side of things (something I couldn't do before). We got the cutting done but had to constantly finger the trigger to keep it going. It would often die at idle (maybe that can be adjusted out). That is a great improvement from what it was doing. Does anybody have any thoughts on what might have happened there?
