Made for sealing motorcycle aluminum surfaces when no gasket is recommended.Adjust the Homelite chainsaw carburetor by turning the high- and low-speed screws as needed. It sets up as a tough rubber and will not break down due to warm oil and is gas resistant. I use the Yamahabond 4 when I have a good flat aluminum surface and no gasket. Not using a gasket glue on thin paper gaskets on aluminum blocked engines will sometimes result in a thin paper gasket leaking after it becomes saturated with hot oil as the engine oil heats and cools, The copper coat is what I use for the very thin paper gaskets when bolting aluminum blocks together on small engines to keep the thin paper gaskets in place permanently over long periods of time as the aluminum heats/cools. You can store the can of K&W in a working refrigerator and it will last forever. This will be the one shot getting the cylinder in place because when the surfaces touch they must remain in place due to the glue contact. Apply a copper coat to the top of the 2nd gasket and let it become just slightly tacky and then also a light coat to the bare aluminum cylinder and set the cylinder in place. I would think about using two gaskets, if using gasket material of the same thickness as your OEM type gasket but I have some gasket material that is about twice as thick that I would consider and clean the area of both aluminum surfaces really good stir up the K&W really good so as to get a copper coat and apply to the block, let the sealer become tacky per instructions then place one gasket and carefully apply the sealer to the gasket in place and let it become tacky and apply the next gasket.

Paying around $12 each for a cylinder gasket that should cost 25 cents is not a good thing so make some spares while in the process and if you are going to play with Homie saws in the future. You can choose the type and thickness of your gasket material at a Auto parts store. Get a can of K&W copper coat 401504, (about $12 some gasket material use a new gasket as a pattern and make about 3 gaskets (one as a spare) Those flat gaskets will not be hard to make. I would try this: IF IT WERE MY OWN SAW AND NOT A CUSTOMERS
