If Im a Husky dealer, and someone has a saw bought new from me, 7 years ago, and it has around 250 hours on it, and it comes in for a service…A service includes nothing more than chain sharpening or replacing, new plug, new or clean air filter, check top no load rpms, clean it up, new fuel filter, fresh fuel, and send it on its way. If the saw goes home, and a few days later burns up, and it comes back to me…I know its not the plug, nor fuel filter causing a problem, nor the chain…so the problem will be either random mechanical failure, improper fuel mix, or abuse…assuming the fuel line is good to go, and the intake boot is good.
