Re: what plugs
QL76V Champions.Idling is hard on the impeller and plugs. It also carbons-up much faster.<br />So change out plugs twice a year with decarbing first.I would replace the impeller anually too,if mostly used at idle and you have over 60 hours a season.<br />Not saying the impeller is bad, just something to keep an eye on if you idle a great deal.
