My choice would be between Redline 53H and YS50ST.
Once you get used to its differences the YS is a great engine, the pressurized fuel system keeps it running very consistent from start to finish.
If you go for a YS, the Hatori #522 is excellent, great power and not too loud.
FOr the 53H, Hatori developed a special muffler, the #523
