Chainsaw Repair

Im thinking about changing out the ignition.  Echo offers both limited and non limited magnetos on their engines, hope to come up with something w/o spending alot of $.  The 'digital' type seem to be the limited ones but the amount of advance is also a consideration.  Current timing is; 11 degrees BTDC at 3k rpm, then 32 degrees BTDC at 8k rpm, which then drops one degree and stays at 31 degrees BTDC at 12k rpm.  13500 +/- 200 seems to be the magic number on the limiter. 

......snipped from a few posts up.

seems like it has a quick slope from idle to 8K, and quite a bit of total advance.  is this similar in most saws?  have tried to put a my light on my husq., with poor results after about 5K rpm.

wish my laptop could 'read' the .pdf.  if i update the adobe on this machine, will run out of memory due to update size.

good stuff bob!
