Dexter: Yep, I had a brand new out of the box 33RSC on it at the beginning of this thread. Then I swapped it for a brand new out of the box Husqvarna chain, whatever their equivalent to the 33RSC is.
Okay, so I had a cord or two of 12" - 18" ash and maple trees to buck [1], and decided this would be a good test for the 036. To date, I've only been using this saw with rounds over 24", mostly ripping (not noodling, but straight ripping) these 1000+ lb. rounds to halve or quarter them, before muscling them onto the splitter. Clearly not this saw's forte, and my comments about it grabbing and stopping in the cut were all with regard to full nose-buried cutting of big stuff, as that's mostly what I seem to get these days.
Bucking up stuff under 14", this saw flies! Definitely one of the higher chain speed saws I've run, and in 10" Maple, it has no problems keeping the chain speed up. I'd say even up to 16" diameter, it does very well. At 18", I see it slowing noticeably, but it still does respectfully. When I get to the full length of the 20" bar, such as the piece in the photo below, the saw is a dog.
The answer: I should have put an
18" bar on this saw. I was thinking a 62cc saw should handle a 20" bar well, but it just doesn't do well with a 20" bar buried to the nose. Unfortunately, I bought a new solid pro sprocket tip bar and about a mile of 33RSC chain for this saw, so I'll have to decide whether it's worth spending the coin to switch down to 18". I do spend a lot of time with the nose buried in bigger stuff, and while the 064 does well with the big stuff, it would be nice to be able to keep working with this saw when it's already in my hands.
I did have some fun drop-starting this saw, something I don't think I'll try with the 064. The 036 has a decomp valve, although I find it's not necessary, and almost never remember to push it!
