Had 029 Super come in for repair. Replaced fuel line, pull start and carb. I tune customers saws by tach as most don't know how to tune a saw. Went in my old 2003 Stihl CD to check max rpms. Max rpm 029S 12,500 MS 290 is 13,500. Both are 46mm. Question is why there a 1,000 rpm difference?

Newer technology. MS290 probably has improved porting and carburetion.

check out these specs too. 029 says 13 029S 12.5 thinking I seen 290 12.5 http://www.getsaws.com/S_specs.html

Just for firewood cutting, I'd probably just set my 029/MS-290 to 12,500? The engine will last longer.

I usually tach them 12.5 just to give a bit of buffer.

That was my thinking too. Port timing is where I think it is carbs are the same on the Super and MS that I have.
