This is something that I concocted several years ago. To this day it has worked great. On my 51 Husky directly in front of the carburetor there is a plastic partition. The long screws go all the way past the carb and into another plastic piece. Well the plastic piece had two stripped screw holes. On this saw while replacing the gas line I discovered this. Well to make it simple I took two 1/4 inch pan head screws and drilled a bit around the plastic. The pan head screws fit easily through the plastic that I used super glue to keep them from turning, then up through the carburetor and into the outer piece that the air filter sets into. To sum it up, it works great. So if you happen to have a situation like this ,use your immigration. It worked for me, Ken
