Hello Gents,
Long time lurker; very first post. Nice to be here....and thanks for all the great advice and information you all impart!
I thought I'd share my tach installation and solicit some thoughts on the job.
First, the finished product:
Yes...this took HOURS! Why can't they make these things square?! But not bad looking, no? I think the tach is supposed to be KTM Orange but it's a pretty good match to Stihl Orange.
So, the question for you knowledgeable guys: The tach does stick down into the air filter space a bit...a good bit...a good 1/4". According to the fancy Stihl animations, air is forced up into this cavity to be sucked into the filter and engine. I have what amounts to a pink school eraser sticking into that air filter space. How will this affect the operation of the saw? The obvious answer is, "go out and run the saw, dummy, and find out for yourself." But I can't get out any time soon, and I'd like to get some thoughts on whether even running the saw in this condition is a good idea or not. (The tach does not touch the air filter element, so vibration won't rub a hole in it.)
(Nevermind whether this is good for the tach or not. Sitting in that incoming air stream may kill it, but if it does, I'm only out $35...and the cost of a new cowling without a tach-shaped hole in it.)
This is an M-Tronic saw, so I'm thinking (hoping!) the carb can "think it's way around" this obstruction, but I have no evidence one way or the other if it will. My plan is to "reboot" the carb when I do get a chance to try out the modification. (I've not seen anyone post the M-Tronic carb reset procedure here yet, so if anyone thinks that would be useful, let me know and I'll post it.)
(And, yes, this is a new'ish saw [just 15h], so it will get an OEM cowling if and when it does go in for warranty repair.)
So...am I headed for trouble?
Thanks!
-Mike
