Started tearing down my open port Husky 55 today. Bought it as a parts saw, because it was bell to be blown up, turns out the spark plug threads were stripped. So I figured I'd pull the jug and fix it and while I'm at it, do some port work and few other misc mods. Has anyone done a timing advance on a 50-51-55? I know STIHL's like about 5 degrees or so, but there's mixed feedback on huskies. Also does anyone have any pictures of port work or port timing numbers to give me an idea of what to shoot for? I don't intend on running it often. Just occasionally to cut firewood etc.....mainly just doing it for the learning experience. I put a 46mm Hutzle kit on a model 50 back in the spring and did some mild porting, but other than that didn't really do any serious mods. I'm just looking to improve my knowledge on ignition timing for 2-strokes, port timing and porting the jug in general. I also may try my hand at hydroforming expansion pipes just for fun. Any and all input is appreciated. I just like fooling around with engines.....my dad is the one who does all the timbering. Thanks.
