Im not sure what this is and i havent received my manual yet for my husqvarna. Can anyone help out and tell me what this big black box is? .. do i need it and if so, what does it do? This is a 13 husqvarna te449 Thanks in advance, David
gasoline vapor recovery canister you don't really need it (unless your state/province/country does emissions testing) but it does not cause any power loss. Typically, they're filled with activated charcoal that "hold" excessive vapor emissions coming out of your tank (liquid too?) and get sucked back into the intake system usually because they're under a slight vacuum.
NP. don't remove it without a good understanding of which "holes" you're gonna hafta block (a couple) and which you leave open (tank vent).
