I worked for echo and know for a fact it's limited. Even Donnie walker makes that statement in one of his videos and gose into detail about it being a good thing.

Why don’t you take a deep breath and dial back the aggression. This is a friendly place to have a discussion. It’s not a place for starting an argument with inflammatory posts. Take that stuff to Reddit or ArboristSite. Thanks in advance.

Any idea what the 7310 is limited to?
Based on my experience with a 7310, it must have a limit higher than 14K. I found that out before I figured out how to rid the carb of the limiter tabs so I could add some fuel to the high jet.

I've never cared for rpm-limited coils in any saw. Nor have I been a fan of any type of governor on carburetors. They oftentimes hinder the ease of tuning a ported saw.

Many Echo coils retard the timing after reaching a certain preset RPM (CS-600 is a good example--they sound almost like they have a mechanical governor: they will over-rev a little and then pull down). Not many are limited in that they cut the spark. The 2511's are about the only that I can think of. The ones that retard the timing are easy enough to tune by ear even when ported.
