The 6100 is a 61cc saw with no decomp. It does have an air purge bulb. Runs on second pull most of the time when cold. The spring assisted makes for very easy pulling.I have no experience with the dolmar 6100.
But the easiest starting saw I've ever ran is my ms260 pro.
Being 50cc and having a compression release makes It so easy to start.. 1 pull and "pop", push in the compression release, flip off the choke and it usually goes on the second pull.
