Well it isn't, technically the problem is with, in your case, LW. Why that is so, LW put the engine on THEIR machine. I don't care who made it, if a manufacturer of a machine puts an engine from another company on THEIR machine, it is THEIR problem. Yes... If I decide to build cars but am short on resources, so I decide to drop Ford engines in them, sell them like that. And for some reason my customers decide the Ford engines have problems. It's MY Problem, not Fords! I am the one who decided to put Ford engines in there. If I want the problem fixed, I have to deal with it. Now I might order Chevy engines in the future, but until I stop putting Ford engines in my cars, and so long these Ford engines give my customers headaches, since I built the car and I ordered the engines, it's my problem. Simple. That's the kind of thing really gets me going. Damn. Out of this world, way out there, really. Maybe they should write Briggs on their blowers then? btw... I am sorry you had to deal with that.
