15-16" is ideal for balance and perfornance on a 346xp or similar - longer or shorter comes with a tradeoff "bill".

Each to his (or her) own, nothing is carved in stone!  ;D

I've been cutting my firewood for nearly 20 years with an old Husky 154 with a 14" bar, 0.325, 0.058".  Just recently upgrading my understanding a little and thinking of getting a longer bar.  The manuals give 18" as the max length.  That might be OK for me,  but I'm just wondering what sets that limit.  Is it the oil pump?

Cheers,
Gregg

No right or wrong here. Everyone just picks what feels best to them.

My preference for 50cc class saws is 16" .325. Gives me the best balance/handling.

I know there is the never ending debate about whether to convert these saws to 3/8 or not, with various reasons for or against. But for me, the ticket is to keep the .325 and switch to an 8 pin rim. About the same extra diameter as a 7 pin 3/8 to provide more chain speed, but without the additional drag of the wider kerf chain.

Interesting thoughts.  I remember working with the portable mill guy when we milled the macrocarpa (cyprus) to build my house.  He had a 154 I think with a shortish bar that he called his limbing saw.  A few years later I bought one from a friend.  Heavily used and beat up looking,  but the engine pulling really well.  I'm wondering if the oil pump capacity sets a limit on bar length?  Perhaps the limit set by horse power or ergonomics/balance comes up before that?

Could be either way. Like a Dolmar 7900 has power for a 32" bar but for good oiling you best stay with 28" or less.

I totally agree!  ;D

I would put a 16" on that one, but I am sure you can stretch it to 20" if you really need it. Balance and handling will of course suffer with a 20".

Thanks Sawtroll,
But I have to put ideas about the bar on hold.  Other things to fix.  I replaced the oil pump (with a used one) and fixed an oil leak a few days ago,  but sudenly it's passing a lot of oil from under the chain brake.

I liked 12" on the 338. 14" was longest I had for them.

I will end up w/a 12" if this other saw proves to be worthy.

Got one,  new/old stock on on ebay. This one doesn't have the tapered nose. 18 buck's to my front door....
