Do you prefer a 7 or 8 pin sprocket, and why?

Its not slower is better but stronger,better oiling and less wear.
Big sprockets is like low profile tires on your truck.

Are any new chainsaws sold with an 8-pin? I bought a couple new saws and they had 6 or 7 pin sprocket or spurs. Maybe it's more of a safety thing; slower chain speeds.

I like the 8-pin on all my saws 45cc 14" up to 122cc 36". I can always let off the throttle if slower becomes better. 9 or 10 pin require modding the bar, or more chain, so my use for those are limited.

Homelite super 1050A .404 8 pin, some McCulloch 82cc came with 3/8ths 8 pin .
I'm sure there's more but just a few that I know.

Yeah, the premise that overspeeding the chain causes this problem isn't real valid. In that case, a ported saw would "out run the tip" because it holds more RPM in the cut.

9 times out of 10, the chain derails from the heel of the bar, then comes off the tip. Now, bigger sprockets make this more likely because their larger diameter makes for a longer distance before the drivers get into the heel of the bar. And with boring, there's a greater chance of the chain chattering in the cut, increasing the odds of the drivers missing the heel of the bar as they come out of the sprocket.

Yes, absolutely higher chances of a larger sprocket causing you to throw your chain more.

If "outrunning the tip" is what you easterners call "throwing your chain" then that's a new one on me.

it must be a local thing. I still have no idea what it means. I’m no logger by any means. Just never heard of it. Still don’t understand what outrunning the tip is referring to?

8 for play/bucking, easier to not overfeed. 7 for felling, need more torque to set the dogs and gun to desired angle. @chipper1

7 pin to reduce getting pinched when bucking.

 

[jakethesnake]

Just always 7

 

[Normzilla]

7 pin for more torque.
