If I had a craftsman saw I’d port it. Raise the exhaust port, lower the intake port, advance the timing, mod the muffler. Learn and practice on the craftsman.
After seeing the porting job that the husky rep did on a 2100 I copied it in my husky dirtbike engines making little changes more and more on each bike. Seeing the changes on each bike I took the next bike and did all the changes on one engine. This was the bike that no one could pass in the straights. I learned as I went with two strokes. I was porting drag race engines long before two strokes.
Heck I even ported my Briggs 8 hp log splitter engine. One day while splitting the blue oil fog fumigated the area. I took the engine apart and found all the ring gaps lined up thus burning oil. I decarbonized the engine, ported it and lapped the valves. The engine looked like new. I put in new chrome rings, crank seal, rear gasket, head gasket. I purchased a new b&s 8 hp engine with a aluminum cylinder the cheapest engine b&s made. The dealer said it won’t last a year on a log splitter. It lasted over 25+ years for me and still running for the guy I sold it too. I always put my left over two stroke mix in it.
