I have an OS 1.60 FX engine and is running super BUT! the glow fuel is too much now and would like to swap it for a gas engine in the 25-26CC range and same weight as the OS 1.60 FX. Since this would be my first gas engine and don't know a lot about the products on the marker now (gas), please help me out with a few makes/models I could choose from. Thanks.
