Having had my chainsaw serviced and had a new set of carburator gaskets also replaced it still cuts out when you use the throttle. I read that the Arrestor can cause this to happen and I wanted to know where it is located and how difficult it is to remove and either clean (with heat gun) or replace. Neither my son in law (a mechanic) will take the time nor my husband(who is not mechanically minded at all) are of any help so I thought I would have a go myself. Carol
