Bought unit used had bad belt replaced belt and pulley on trans when unit goes into spin belt slips and you get a burning rubber smell. looks like there is a adjustment or actualy feels like for the spring on the idler should that be tighter may be?if so how do you change it can it be done with out pulling the drum out. Belt is correct factory belt made to slip but watching it it takes a long time to get up to speed and is better when hot as in after it has run thur one spin cycle then you put it thru another it seems a little better. I saw one coment about the drum bearings being tight and causing this also . any info appreciated.
