Yep, Dave is a Very Reputable seller.
I bought my 3120XP from him, and have been Very Happy with it
Note, Ignore the owners manual about using Choke AND Throttle Lock for Cold starts.
Choke ON, Throttle Lock OFF
about 3 pulls, she will snort,
Choke OFF
2-3 pulls she will wake the county
Try the above first, your saw may like something different, I just about had a coronary trying to start that Beast using the Choke and Throttle lock, which is what my "Old Reliable" 266XP LIKES, but not the 3120XP. Even with the decomp valve pulling on that thing very many times will flat wear you out
