That sounds quite logical. Decision for outboard as a sacrifice of user friendliness in favor of better cooling (and thus improved longevity) and a little weight reduction.
Would there not be more leverage on the clutch side bearing by moving the clutch outboard,
Thanks Mainer, nice score on the NOS carb!Good running 490 yah got there. Nice sized saw log too.
Just scored a new old stock hda 45 carb. It's the largest one for the old 1980's cs 8000p. No need in a ported saw breathing through a straw.
How's the snow pack down south? Ain't settling much up here. Still getting stuck on machine, trying to break trail to my next cutsite. At least the trail is set up like concrete today, still winter out there: 10-20 below zero at night.Thanks Mainer, nice score on the NOS carb!
Winter was pretty mild down here this year...but lots of thick wet heavy snow. It's still mostly ass deep. Few more days and hopefully it'll start melting. Looking forward to the long days.Have any projects planned for this summer?How's the snow pack down south? Ain't settling much up here.

Dang! What a difference. Ought to really breathe now.Wow dude74, that 490 is exactly what yah need a 50 cc to be for Alaskan conditions. Yep, i like your recipe, keeping the torque down low.
Too high of rpms, saws run like sht up here in below zero weather: flywheel moving too much cold air, saws won't run at temp even with a flywheel bib. Hard to tune, etc. The density of 20 below air is insane. In frozen alaskan birch, if the rpms be too high in the cut, chains just skip and chatter, no matter the raker depth.
Anyhow, still wrenching on this dmn QV 8000. Went to disassemble the clutch to install a new clutch spring, and found that the clutch hab was broken. Waiting on parts yet again.
The two plastic carb blocks were slightly out of round from over-tightening the carb mount screws. The throttle and choke bore is so large on the hda 45, that both the throttle plate and the choke plate would hang up. Had to take it all apart, slightly burr-grind the carb blocks round and put a bevel on the surfaces closest to choke and throttle plates.
HDA 153B vs HDA 45:
Saw went blubbering rich 2.5 turns out on high jet, with the new hda 45. I could care less if the cs 8000 was quad port or dual port, but would never port another one of these 8000's without a good hda 45.

Hopefully your clutch parts show up soon. Looks like spring will finally be here next week!
