Old trimmer,lots of blowback from carb
Suspected leak and poor reed sealing causing fuel blowback from carb at full throttle. Now sure of diagnosis but it runs some better. Compression good.

I removed the cover, and air cleaner. Removed the fuel lines, and removed the carburetor. Installed the new carburetor, then put the fuel lines on and put the cover back. When I was in there I wanted to make sure the piston and cylinder were good, they were so I bought a gasket to seal that up.
