Well, it's normally me offering advice on repairs, but on this occasion I am after a bit of advice myself.
We have had a new customer approach us about servicing and repair of their farm hand held stuff. Initially the call was asking if we would do Stihl...which we do. Upon arrival, the maintenance manager brings into us a couple of Stihl machines, plus two Husqvarna 562xp saws.
Now, we used to be a Husky main dealer, but that was near 20 years ago, and pre dates all the electronic gubbins they now fit to their carbs. The two 2020 manufacturerd 562's have this auto tune carb system which my guys aren't familiar with. I took them in because if I didn't it would mean we may lose the rest of the machines....although I did point out we haven't done Husky for sometime. I was assured it was just to service and get going and make them ready for two of his guys to use on a forthcoming CS30/31 training course.
We have got to the point of getting them both started, although we haven't thrown a full service at them yet. They both start BUT one has got a very slight hesitation from acceleration on idle....and I mean very slight. A millisecond before it revs up cleanly....but I know it's there.
The second one, again starts and revs up and accelerates cleanly but slowly dies on idle.
My guys have said there's loads on places like this one and you tube videos advising on how to approach issues with this auto tune system, and highlights some of the issues we have with these two. Particularly the one that dies on idle.
My questions is....do we 'have a go' and hope we sort the issues by taking this internet advice, or should I be upfront with the guy and say these two are best left to a Husky dealer?? I don't want to play around with them in the hope the issue is cured permanently, only to find in a couple of weeks time one or both play up during the chainsaw course....and of course the inconvenience and cost of that involved?
If it's considered a simple fix and a common one, then I don't mind but it's my name above the door so want to do it properly or not at all.
