I thought I would post something since we have been quiet on the EFM link. Today was a good day for cleaning my efm. It takes me about an hour cleaned the baffles with my brush took the stack off, cleaned the lower rear back and usually I get about a tub full of fine powder. This year it was less than half. My shop vac gets a good workout. I will probable do it again this fall. I have an older unit 1966. I run it all year. I was wondering if most of you keep the metal hood on the motor area? I keep mine off and it sets in the corner of the cellar. I guess I like to see the parts moving and easier to oil.
