"Optimal" bar size for smaller saw?

    I have another thread going about a free Poulan saw I was given with an oiler issue. I'm waiting on some parts before I can move forward. The bar and chain are pretty worn due to the oiler issue, so provided the repair works, I'll be buying a new bar and chain.

    This saw has a 16" bar when I see most new saws in the 30-35cc category have 14" bars. If I do end up buying a new bar/chain combo, am I better to stay with the 16" or would a small CC saw perform better overall with a 14"?

    I'm thinking a 14" bar and chain will have less drag and bite for the 32CC engine to cut through, so more power will be focused on cutting. Or am I splitting hairs and 2" doesn't make a difference either way?

    Thanks! :cheers:

    I like my stock poulans in the 30cc-33cc range to wear 10"-12" b+c's. My 36cc-38cc ones ran 12"-16", 12"-14" was best. I wouldn't go bigger then 14"

    Poulan is known to put to big of bars on their homeowner saws. Us homeowners always think more has got to be better.

    +1 on the 10-12" idea. In selecting a bar, aim for a 3:1 cc:inches ratio, and you'll be about as happy as you can reasonably expect to be with that saw.

    I'd run a 14" personally. 16" is far more than that saw can push. If you ever got anywhere near full bar it would stall out the clutches.

    Thanks, you guys are confirming what I was already thinking about going to a smaller bar. Plus the shorter bar/chain is cheaper! :clap:

    I'm waiting for parts to continue the teardown and rebuild, so hopefully everything works out and I'll have it running by next weekend (parts order was shipped later than I hoped)!

    That seems pretty accurate for hardwoods. However the PNW's softwood ratio might be closer to 2:1 cc:inches. Another calculation they use is > 30cc's = full wrap. Mr. Troll's ratio is probably closer to 4:1. ;)
