So muffs and pipes aside, another of
@Heffalump 's interests - performance.
I just looked at the numbers for HP for the 036, and the ms361. Both identical at peak power, i.e. 4.6 bhp. But the cubic capacity of the 036 is a tad more, and revs characteristics seem quite different, according to my manual max revs for 036 is 13k, and for the 361 is 14k. Clearly they are both very different engines?
I was also wondering about the potential for very slight mods i.e. to bring the squish tolerance in to ~0.02" and perhaps very slight exhaust and inlet port "treatment". In that case do you think that it would ok to let the 036 rev somewhat higher (13.5-14) as long as it's running a decent mix and rich enough?
