I have a Stihl 020T chainsaw that does not want to run when I open the throttle. I have cleaned the carb & put a carb kit & a fuel filter in it but it still will not take throttle. It acts as though it is running out of gas. This saw has a tank vent that consists of a fiber plug that goes into the top of the fuel tank and then a rubber "vent" that goes up inside of this fiber plug from the inside of the gas tank. It supposedly keeps the tank at a constant pressure. I had to order the rubber "vent" and have not received it yet. Could this be the problem?
If this vent does not cure the problem, does anyone have any suggestions? I am running out of ideas.
