Don't try starting it without a belt , it will break your fingers. It is all to do with how the decompressor works for some reason on these belt machines. Never had a problem with a full crank one but obviously some people have. After trying several decomp valves I finally tried one with the brass restrictor in it and so far not one kickback.
Hi NormK,
I know this might sound like a silly question, but do you need to yank the hell out of the starter when starting these? Or is it a nice gentle easy pull?
