I fixed an old 056 for a local tree service today (uh oh, a "side job" ).. He's had it since new, loves it dearly, but the Bosch ignition has failed - works great for 15 seconds then quits. Can't buy them any more and most used ignitions of that type are on the way out. Replaced the flywheel with the later type, and an ignition from a TS360 cut-off saw. Three pulls... Whrrommm! Damn that felt good.
Hmmmm... my bench has been cluttered with parts from 3-4 056 super and mag2 for over a year... Time to get that old junk blowing smoke and throwning chips. I figiure I have enough to build an real nice mag2 (56mm bore) and maybe a Super (54mm.).
I HATE working on flithy saws... make a mediocre living out of it, but I'll be damned if i'll do it on my own stuff. Time to clean up the mag2 engine.
I'm not sure if I'll spit it parts as it's pretty nice inside, and as saws go, it's only about a 7 on the filth scale.. and if I do split it, I want it clean so so no crap gets inside..
First seal up the inlet - tied-off bicycle inner tube and the boot clamp, the exhaust -064 muffler spacer and piece of rubber, and the plug - hey let's just use a spark plug!
Plug a pressure test bulb on the impulse connection and get some pressure in that engine. Hmmmm.. won't hold pressure... but good enough. With a small amount of pressure, I can dunk this entire engine into anything, and nothing will get inside.
The orginal... sealed up
After a little brush work with disgusting old gritty solvent/gas mix. Who cares, it can't get inside...
Into a 5 gallon bucket of very used purple cleaner - hey, bubbles.. keep the pressure up...
hit it with the gargen hose...
Not finished yet.. into the ultrasonic cleaner with clean ('ish) purple cleaner to bust the crap off the cylinder fins.
more to come..
