Determination, perseverance and a sudden desire for pure pain and aggravation forces me to continue to get my %$#@* Stihl 056 running reliably..........oh, the need to cut too many 20-26" diameter maple & oak trees helps also. My old reliable McCulloch 610 requires too much effort this type of cutting.
First problem was solving the infamous Bosch ---I run until I don't ----- ignition. Fixed that with a design change although before I finish this post, I might convince you that more changes are needed....maybe! So with all my known problems under control, I started off again. Now remember, I am no expert on ANYTHING especially cutting wood.
So I took my trustworthy 056 to one of those trees I mentioned above and cut the sucker down! Next without cutting up the first tree, I dropped a second. Next I took old trustworthy to the task of making big pieces small. Just the sound of that that nice raw alone made my day until the bar tip hit one of the felled trees, knocked the chain off the bar and before I could shut the pig down, the chain continued fly in the air, whipping around as I fought to close the choke ...bad shut off switch. Yeah, I did finally pick up all the pieces.
My brand new 24" chain got chewed up to the point where it could not fit into the bar. So I got out my grinder and ground off all the rough spots only to see many spots where the chain fits into the bar shortened but I thought it would be OK. NO, not OK! I installed it and found I could not move the chain because it was getting hung up in the sprocket.
Next course of action.........2 each new 24" chains along with a new chain sprocket. Where would I be without all this excitement and fun? Now back to the wood pile, better make that trees on the ground that need to be cut to make the wood pile.
Finally with Old Trustworthy humming if one wants to consider a 056's RAW humming, I started cutting. And that thing can ...could really cut!!! I was going thought these logs with ease. 18-20" cuts in a matter of a minute or two until what sound like a SHOOTGUN....BANG!!! The saw blew the muffler off!! I didn't want to stop, muffler or not so I restarted the pig and went about cutting until the next time when it blew off the carburetor cover and stalled!
Damned! Another adventure! It took awhile for me to decide that I needed to look at the ignition so back to my work bench. I thought removing the flywheel would be a piece of cake....did it before. But after several whacks followed by several more, I was able to remove the flywheel! But now a funny thing happened on the way to the forum! The crank shaft seems to bind a bit when I rotate it. I believe I damaged it...........ready now to puke.
So this is where I am at as I type......for those of you who got this far.........! I just order a crankshaft/case for $35 + ship from Ebay. I intend or at least hope to move the piston/cylinder combo over to the replacement case and reassemble this thing of mine.
But back to the ignition because that is important. What I believe occurred is the spark became random and caused the backfiring...forward firing or whatever you want to call it. And I just posted a solution to the ignition problem or at least a solution to the problems known to me at that time.
There are two electronic circuits in the ignition. The first circuit, the one that I believe was the cause for lack of spark is designed to store energy that is used to develop the spark. The second circuit is energized by the rotating magnets to discharge the stored energy. My hunch is the second circuit has a component failure that will result in the discharge switch firiing at random. This is a long wordy post where I have tried to add a little humor needed to control my rage with the 056. But it is important to know if others have had a problem with the 044/056 blowing the mufflers off. I will post a separate discussion to see if this is more common than I believe.
That's about it : -(
