”M-Tronic Failures”

Exactly what dealer said. Got to see one, all oiled up and running out of the muffler. I work em but don't abuse them. Try to keep them happy with sharp chain and maintenance.

 

My 362 was a demo and already broken in when I bought it. So it was WFO from the get go when I got it.

It is a damm shame that Sthil dealer are just plain ignorant. They call me all the time for information on various saws ect.The first thing I ask them is how did you get your certification from Sthil to be a dealership. Sthil has been for the last several years sending all technicians to school, and dealers also so they will be able to diagnose there products, and how they work! What is stamped on your module? 4700 D? Have a nice day!

Boy I remember those mfg training classes back in the day- class all day,party all night. One notable time ( 2 week class) about 1/2 of the class didn't show one morning, there was a unmentionables modeling show at the hotel the evening prior...............

 

That was a picture of my coil. That was a 4700 D.

 

I will tell you what we have done in the pass to fine the real problem, please don’t laugh. If you take your module off the saw and put it in the refrigerator and let it get cold, then put it back on the saw and do the calibrations that I wrote in one of my Posts you may see a big difference in run time before it starts acting up, and if you do you will know where your problem is. The flooding doesn’t always come from a bad boot, it comes from the simple fact that the module is not letting the saw fire and the more you try to start it the more raw fuel is introduced to the cylinder/piston. That’s why you hear a lot of times people (quote) say that if they wait 30 minuets or so the saw starts and runs, that because they are letting the saw de-flood it’s self. The module plays this part usually when it gets hot, and saw dies @idle. I am experiencing with my own fix that my or my not fix the problems, it is with a standard coil with a chip right now it R&D. But if this works it would require a carb that you would tune with high & low jets and idle screw. Which would make it a non- e.p.a. saw. For all you reading this Post that’s what you are buying when yo buy either a Sthil with M-tronic or,Husky with Autotune both are E.P.A. saws. Have a nice day...

By the way I was fortunate to have bought a brand new 660 straight from Germany about three years ago, it was a non-E.P.A. Saw it’s the one I wrote a Post on the “Boss Saw” 660 of course we ported it it and put a gutted dual flow muffler on it and it screams, to say the least!
Have a nice day...

That freeze-up trick has revived more than a few electronics. Recommended.

 

Great info Stumper thanks!
