RE: I converted a glow engine to run on E85
Yes OS Engines is coming out with a .55 engine. There is a web page showcasing the new AX-55BE engine from OS, I can't find it but I have seen it. They changed the combustion chamber, probably to increase the compression. It's funny that they say it has more power than their .46 engine. Those new glow plugs will be interesting. I wonder how long it will take for someone to make some biofuel glow plugs in standard sizes.
