Carburetor is part of the
emissions system and is warrentable for 2 years...
Found this out a year or so ago when I replaced a customers fuel line on his 361 and had no idea when he bought it...
Charged him and off he went, next thing I know I am on the phone with Northeast Stihl asking me "Why I charged a customer to perform the repair on a 6 month old saw".
The guy had thought about it and instead of asking me he went directly to the company.
my answer was, "He didnt buy it here, I didnt have a purchase date and the fuel was completely dry rotted/cracked and leaking fuel."
I then said "Wait a minute...commercial warrenty is 90 days"
the answer..."Emmisions is 2 years"
hmmmm
