2145 bar and chain

[Freak007]

Hello, I have a Jonsered 2145 that currently has the original 16" bar and chain on it. The chain has seen better days, and I am thinking about replacing it with an 18", but I'm wondering if this saw has the power to effectively run a 18" bar when limbing and blocking up deadfall (mostly white oak and pine, much of it in the 18-24" range) I am leaning toward the Bailey's 20SC or 20NK chain. Ultimately I want to add a 65+cc saw with a 20-24" bar to toolbox, but for the time being I would like to start with a longer bar on the one I have...

Thanks

If you are mostly doing pine it will marginally pull an 18". In hardwood like oak I'd stick with 16".

That's kind of what I was afraid of... Will running the .325 narrow kerf chain make enough of a difference to allow it to be efficient with the 18"?

For reference, I also have a 51cc Remington "Rodeo" that wears an 18" bar and as long as the chain is sharp and I am not in a hurry it does fairly well with what I do. Im not sure what the power rating is on that saw though...

Again it will be fine in softwood, marginal in hardwood. But I do believe the NK will definitely be better than the standard chain.

That Remington is probably on par with the 2145 in the power department. I didn't see a HP rating when I looked it up.
