Here For The Long Haul!
Back in June I got some help tuning my 2172 and it seems like everyone agrees that the bottom end can't take much more rpm than 13,500. Has anyone had one tuned to a high rpm and had the bottom end go? I was thinking that if I tuned it like an oe 372 with an unlimited coil, say I ended up around 14,500, then put the limited coil back in there wouldn't be any chance of going over 13,300 when cutting smaller stuff. Could the bottom end take that setup? Mine is set at 13,450 now and runs good but it runs a little better and is still rich at 14,000. I'm sure I could lean it out some more and it might run even better but that saw going to stay where it's at because I want it to last.
Here soon I'll be rebuilding a 2172 and It's going to be ported like the first one I did but was thinking about trying to get the max rpm in the cut with it. Any thoughts on that? There's just not a wealth of information out there on ported xtorq saws. Maybe because they just can't take the abuse but I've yet to find a thread where the bottom end has fail on on a ported one. If anyone knows of such a thread please point it out because I would enjoy reading it.
