Dump the Stabil(junk) and your problems will go away. Since I quit using Stabil and went to Seafoam, all of my carb or injector problems have gone away. Always had problem with any engine stored over 3-4 months using Stabil, now I have gone as long as 16 months with Seafoam and had NO problems.
When ever I know I will not be using an engine for more than 3-4 weeks, I mix the correct concentration of Seafoam with the fuel and let it run until I am sure it is throughout the fuel system then shut er down and not worry about it. This applies to all my gas engines, from the small ice auger to the car and truck.
