I’m looking for a little help with determining what’s going on with my 462. The saw runs and cuts “ok”, but has become sluggish off idle. No longer has the lightning quick throttle response and acceleration it once did. I don’t have any repair manuals for anything m-tronic to see what stihl shows for a correct diagnostic path.
I’ve done the recalibration several times since the weather has been anywhere from 40-80* in the same two day period here lately.
Timing is (was) advanced about 6-7* and muffler modded. Roughly .700” diameter hole in stock location. I put the timing back to stock to see if it had any affect on the situation. No change.
Changed plug, no change. Color indicated a good tune.
Pulled carb, no dirt found in screen, everything looked fine. Fuel line is not restricted.
Fuel is same batch that runs fine in other saws.
I’ve exhausted all the simple stuff, so now I’m down to blaming the coil/ecm or the carb solenoid. Has anybody had a coil fail that still ran but was doggy?
The saw has about 12 or so tanks on it. It ran good stock, ran really good after the muffin mod and timing adv (about 3 tanks that way) and now it’s just irritating me.
Thanks guys.
