The diesel head I got from Hobbsy came the other day. I cleaned it up and will bolt it on and run it on Monday. I have a reasonable pile of props to run. I'm curious to see how my engine runs. I have another higher compression glow head I'm gonna try before I dieselize the Fox .50. I have a feeling the carb may be too big for Diesel use, but I'll find out. It's an MkX C .330" choke.
