Hi There, I have a Home Lite HL80835 that I bought from HD about 2 years ago. The issue I'm experiencing is that as soon as I fill the tank with gas, all of the gas immediately drains out between carb and the body of the engine?? Gasket still looks to be in good shape and bolts are tightened really well. I don't want to keep tightening them for fear of snapping them off. Any suggestions??
