Hey guys,
New here posted the other day and I really appreciate you guys being here.
I have a 330 that I just resurrected and was wondering if there is a .325 pitch sprocket and bar/chain out there in 16" length? I don't see any Mfg. as producing this. Thanks in advance for any replies.

If you want to run .325 pitch the Oregon Drum is 30685X for the 330 and once you have a drum the rims are:  You may have to look harder for bar with at .325 sprocket tip. Why the 325 and what gauge are you going to run? |

A .325 sprocket nose bar in that mount is tough.

Thanks for responding guys. I was thinking of the .325 pitch for firewood sawing. In comparison to my old blue sxlao this saw does not clear chips at half the rate old blue does, but I like the vibration limiters for long sawing events. I figured if I narrowed the kerf a bit and put a 16" bar on her she might be able to handle it better than a 3/8" but if experience and use show differently then please let me know what is a good setup for cutting almost exclusively dead red oak, ash & maple. Our woods are full of standing and downed hardwood trees so cutting green wood is not something we do much of. I was looking at a GB 16" bar & chain combo in 3/8'. Is this the setup I would want. Thanks again for any replies. I am also going to do the muffler mod, anything else I should do to this saw to wake it up? I just did a carb kit and carb boot so she runs properly at this point. Thanks again for any replies.

I don't have any experience with the 330, it came out after I got away from the business, but it has the same size engine as the XL12 so I don't know why it wouldn't work well with a 3/8 chain on a 16" bar.

If i get the Oregon drum and get both 7 & 8 tooth sprockets for 3/8" what is to be gained form switching tooth count. What is the best combo you guys have found for the 330 saw?
thanks for any replies.

7 tooth = a little less speed, a little more torque
8 tooth = a little more speed, a little less torque
I think that you would be happier with the 7 tooth/16 inch bar, unless you are always cutting smaller wood. In bigger wood,
it might bog with the 8 tooth, unless you had a lite touch.
Rim sprockets are cheap- buy them both and try them.

Same idea as a being in a higher gear on a car/truck/motorcycle,etc. Only thing is that your saw has to have enough power to turn the chain at this faster RPM since it will require more. Bar size, type of chain, type of wood, and as always, sharpness of the chain along with raker height all play into whether or not you'll actually cut faster or slower with a different tooth count. I've only used 7 tooth with a 16" bar n a 330, so I can't tell ya what will be best. Can't hurt to play ;D. Dan |
