Love my 620PW, but got the itch to port/polish, etc the 620 and 501. maybe the 7310 eventually. Who are the top Echo builders? I'm in KY/TN area.
 
TAKY - how did you fare against the tornado last month? I was clearing trails today in Land Between the Lakes and finally got to see the devastation first hand....its unreal!😥 I don't know how the forest will recover unless they burn it (?) It looks like God ran a string trimmer from Kentucky lake to Lake Barkley.

No issues for me, but a lot of people have been displaced and some have lost loved ones. It is amazing to see the trimmer effect on huge mature trees like they were blades of grass. How about you?
 
We were fine also. I went to Pembroke the following day and it was crazy, but nothing like Bowling Green and Mayfield. I had seen aerial photos of LBL but seeing it today in person was unreal.

Not sure around Ok. I build all my own motors. My next ventures include getting a 3d printer for making big intake manifolds and filter systems and I'm also wanting to start making my own bolt on cylinder domes to precisely control squish and compression. Plus billet heads look dope af. One day I want to get a 620 and do a true side by side comparison with the 590. Id get as detailed as to hook a timing light to them to look at there advance rates and peak degrees.
 
Long time lurker… and echo owner, finally joined. Wanted to say thanks to everyone that has contributed to this post/site.
Bought my first echo product 15+ years ago… srm225 string trimmer ( went through 3 trimmers the first two years I owned my home ) decided it was time to buy something that would last… the trimmer is on its 2nd spool head (1st broke last summer) and it’s started with 2-3 pulls since day 1. Blower is 8+ yrs old. CS620PW 28” B/C is still being broken in… (3 tanks) and CS400 18” B/C is brand new, still on the first tank. I got a steal on the 400… $125 NIB on Craigslist.( it’s a 2013) the guy found it in garage while cleaning out estate… box had never been opened…

every piece of echo equipment I own starts in 2-3 pulls cold and 1 warm every time.

How does your 620 do with the 28" bar?
So far it’s had about a tank worth of 20”-24” pine and had it burried in 36+ 2yr seasoned red oak, no bogs or hiccups of any sorts.
Only issue with bar is it’s for the cs7310 which is 9mm vs the 620’s 8mm studs.
I just made some adapters out of plate steel to limit the excessive play. 1DFB3506-7247-4542-942A-71B8707C878C.jpeg

I made some bushings for my 620 out of some brass tubing so I could run Husqvarna bars on it.
