i have a eb400e, you know the old orange one that is super loud and super heavy. it has been a great blower, i used it for a couple of years, but it hasn't ran well this season. it surges really bad, hard to crank, smokes and won't rev up very high. does anyone know what i can do to fix it, or do you think i should hang it on the wall as a trophy and buy a brand new one. I guess what i'm asking is, if its something easy and cheap to fix, i'll do it, but if it needs major work, i'll buy a new one.
