... I`m not aware that you have any experience with this gimmick.
Unlike some around here, I'm only a two-<u>working</u>-saw man. They are both on the truck all the time and get used to make money or to help out for the most part, with rare forays into entertainment. They are both recent Stihl models which have the gimmickry. I've worked alongside older Stihl models which are not so endowed and have seen first-hand the difference it provides. I've also got some years on older Homelites which worked the same way.
I still feel that it is a feeble attempt to counter the success of Air Injection and Turbo air cleaning as you will find on current Elux saws.
What did Partner call it before Elux got them and put it on those two other lines of saws? (hahaha)
I know that I`ve seen it in print in the early days of the Intellicarb that it will extend the cleaning interval and I know of no less that four Stihl service school trained technicians who state that this is what they have been taught to believe.
I'm not familiar with the early (mid '80s?) advertising and am not privy to what gets taught at the tech school; I'm self-taught in this matter. I do believe marketing does not always end up being entirely factual and agree that market(eer)ing is a powerful influence.
... he seems to believe that there is some benefit to running a saw with a dirty filter if the air/fuel ratio is compensated by a system such as this.
Unlike continuing to use (because there's only a dozen more cuts to make) a chain that's become "a little dull", this situation <i>is</i> better for such a scenario concerning the air filter.
I`d rather have a system that falls on it`s face a little more when it finally gets dirty enough to see reduced air flow than a system that discretely detunes a saw from the first moment that it is placed in service. At least this way I can stop and take the couple of minutes it takes to knock the crud loose from the filter before it is totally impacted, impacted the way that I`ve seen it many times on Intellicarb equiped saws. Running an Intellicarb detuned saw is like continuing to run a saw with a dull chain which keeps getting more dull. Performance loss may be gradual, but it exists none the less.
I don't believe the system detunes the saw until it's necessary and when it is, the level of "detunement" is less than would otherwise exist.
The first thing I check when I notice the saw's not cutting as well as it should is the chain. I guess I can't recall a time in the last several years, at any rate, where the filter hadn't been cleaned before a noticeable drop in performance. I highly suspect the same goes for you.
Cleaning the filter on an Intellicarb saw usually means compressed air and carb cleaner to get the deeply impacted dust out and although this method will restore a filter to nearly new condition, it also shortens it`s service life. It all comes around to smaller bits of preventative maintenance versus an overhaul in my opinion.
Much the same way that for most, sharpening a chainsaw blade means taking it to the store and having them grind it.
Good to see you back and in good form, Russ! Can you round up Fish, too?
