A buddy of mine got an old auger with a 2stroke that had been run on straight gas and burned up for free. At the time he worked in the service shop at an equipment rental business so had access to lots of parts and knowhow. He cross referenced some part numbers and found out that a motor of the same make that they used on the gas concrete saws used a bigger piston. He tore it down, decked everything and bored it for the big piston, tweeked some stuff here and there and redid the carburetor. That machine sounded like a lumberjack contest hot saw, and would cut a hole in 2 feet of ice so fast you thought it was going to suck you down the hole.
I missed getting it by a day when he moved south, gave it to someone else the day before.
