Question, will the engine run when the blower quits or are you dead in the water. Also I read about a plastic devise in the blower that is likely to go first. What is this part and could you just replace it or shoud you replace the whole blower? The last replacement quote I saw on the forum was for a new blower and the price from a dealer was listed at $550. this seems cheap to me, anyone else get a quote from the dealer Please???
