I have a Stihl 051 chain saw sitting in the corner of my garage. Its an old one it was my grandfathers. Some one borrowed it once and dropped a tree on it, cracked the case and handle a little. Still runs good I don't think it has many hours on it as it was his backup saw.
Has anyone here ever converted one. Any specs or suggestions? Stihl web site says 5.4 ci

I don't like chain saws I like airplanes!

Thanks in advance for any info.
Pete
