Pawn shop find (looked "road hard & put up wet") so don't know history (it started/ran seemingly good, $100 out the door), new fuel tank, cleaned up the rest, fabricated inner/upper dawg attachment point, opened up exhaust hole to 3/4", then slapped on 1x previous (15 cut) use w/o issue (044 saw) 24" Laser ultra light (Tsumari light) bar (chain as tight as I've been doing for years, smooth "finger pull" w/o "slop").....fired/warmed up, hooked up "cheap" new tach (idle 2600) then "ran it up" a few times to see where it's at (would hit about 10 1/2-11k, then "stutter" down, I figure "4 stroking" due to exhaust mod), noticed an "unusual smell" (sort of like "burning oil off a new part that heats up"), shut off, chain tension seemed fine but bar was pretty warm, pulled bar and "dirty" oil was "splattered" backwards around clutch drum and inside cover/60% of bar rail top&bottom were "black" (90% sure it wasn't like that from bars 1st use) & didn't seem "oiled" at all....cleaned oil up & tried again, almost identical result except "clean" oil splatter and bar rail seemed to have a little oil on 1st 1/2 (mainly) this time.....pulled the bar & ran to confirm oil flow (which I have no previous "eyeball" experience to compare it to) it does "oil"....tomorrow will grab the 044 to compare oil flow & try it's "inner bar chain plate"......Any shared info would be greatly appreciated, Thanx in advance

The original black color was probably from the previous owner running used motor oil for bar lube. I would pull the clutch drum off and make sure that it doesn’t wobble back-and-forth much so that it can still drive the oiler worm gear. Make sure the worm gear tang still reaches the notch in the drum. And make sure the threads on the plastic worm gear are in good shape
