A few months back I decided to rebuild the 045 Super I bought years ago along with the semi working 056 Super parts saw I bought a bit later. Both had been the bane of my existence til I retired them, as I learned about their faulty ignition design, unobtainium bearings/seals,etc., while hopelessly trying to get them to work right. Had high hopes once I finally got NOS bearings and seals, Foggysailed one ignition and got a German aftermarket Sagenpezi for the other, and got new jugs and pistons. Tracked down every little missing odd and end to complete them both. Then to my profound frustration, neither worked even as good as they had before, or even at all to start with. Fixed some loose ignition wiring and got spark and some life, but then months of cleaning, rebuilding carbs, taking them on and off, trying different jet settings, trying to get them to run consistently, I'd keep discovering little problems that got them running a bit better, but always always always spitting gas out the carbs and never reliable.
Finally accepted the carbs were not likely the problem after rebuilding three and buying another rebuilt one, I did what would have saved me months of headache and bought a $75 Mityvac kit. Found the ignition side crank seal wasn't seated properly at all and the clutch side was leaking from between the outer race and casing. Took advice given about an old 064 with the latter problem and put Loctite around the outer race and pumped up a vacuum to draw it in. Seems to be holding vacuum real well now. Wish I'd paid attention to all the talk of pressure testing crankcases, thought it required more specialized equipment than it does. No point in ever fully assembling a saw til you know the crankcase is well sealed.
Anyway, will be a bit of time before I get the first one all back together because I have to re-do the Foggysail fix since I never secured the capacitor and wiring to the shell of the saw well enough and one of the wires partially got shredded by the flywheel. But fairly confident that after untold time wasted, I've finally gotten on the right track and will get these saws back to their original glory that I've never seen. Also wish I'd discovered ultrasonic cleaners before I started all this, one of the best inventions I've come across for small parts cleaning.
