I sacrificed my clean truck for a log to test this 420 in, lol
. I touched up the chain with a file on a jig for a nice clean reproduceable edge. The wood is a little bit splintered on the end, but this was best I could do for tonight and I want to get going on this thing. I'll be out of town next week for work. I tuned the saw right up to the limiter at about 13,100.
Actually the first thing I did with it was to swap on a 5100S coil in order to move the rev limiter higher. Strangely, the saw wouldn't even run. It had spark but would not fire. So back on went the stock coil.
After timing the saw as I received it, I then modded the muffler and retimed the saw. The results were interesting. Giving the saw a normal bite as you would in normal use, I only picked up about 5% or a little less. But when lugging the saw down, I picked up 13% to give the best time of the evening. I even bested the time of the ported Redmax! That 190+ PSI is really shining through.
Next I'll be pulling it apart and porting the cylinder. More timed cuts will be coming after that.
