    Those 2 statements are contradictory, no? So which is it, a larger sprocket gives faster chain speed less torque while a smaller sprocket goes slower with more torque, or vice versa?

    And, Is the chain speed changing because the saw motor is changing rate (rpm) based on the amount of resistance caused by the sprocket size? OR, is the chain speed changing because of the change in distance it is traveling around the bar/sprocket, similar to gearing on a bicycle chain?? Or is it the change of angle the chain has to do a 180 on (the sprocket size) that causes the difference.....? This is like a puzzle!

    The smaller diameter sprocket gives the feel of more useable torque in the saw to pull a given size chain. A larger diameter sprocket gives less torque at the chain on same bar to pull through cut.

    I should of said you needs a big saw with lots of torque to pull the big pins through the wood.

    If your not in huge wood and the saw has torque to spare you can give some of it up for chain speed. Basically were all saying your saw does not have the excess torque available to take advantage of the extra chain speed on said length of bar. If you were to go to say 16" east coast bar. Throw an 8 or 9 on it and see the difference.

    And you analogy to a bike gear applies its something to do with the gearing and circles and complex math or rotation circumference and speed of that gear at a given rpm

    7T should be ran on smaller saws or even bigger saws with longer bars.

    The smaller the rim sprocket, the more torque. The bigger the rim sprocket, the chain speed increases (same as sprocket gearing on a bike, dirt bike, ATV, etc). But you loose that torque and the saw will fall on its face a lot easier.

    A 60 cc saw with an 8 tooth rim isn't gonna be any faster. The chain speed will be faster (out of the cut), but the loss of torque will yield a slower cut time.

    Unless you have a strong 70 cc saw running g a smallish bar 25" and under? I'd stay with 7T.

    90 cc and above, 8T makes more sense. But even a longer bar (36") will work better with a 7T.

    When in doubt? Run a 7T.

    Oh then thats a 7. I think 7 is standard on all the saws that are like 261 and up. The baby saws I'm not sure?

    Yea I know that. But I thought I accidentally wrote 20t and not 20" and he went back to my post and corrected. Yet quoted the wrong text. Was just confused. Yea I known you can change quotes. I only usually do it to just quote a piece of a larger quote.

    i tried an 8 tooth on my 272 with a 20" bar and it was noticeably more grabby and easy to stall. i immediately went back to the 7tooth. i wouldnt use an 8tooth unless i had 80cc+ ported saw. i too enjoy the feeling of being able to lean on the saw a bit.

    great video by brad snelling showing the lack of significant difference even on a strong ported 77cc unit.
