[QUOTE="Trfsrfr, post: 211271, member: 3959"] I just repacked my boys CR80 tonight, got the packing from RMATV in 2 days for $3.99, a 12x15 piece. I cut the piece into 12x7.5, rolled it up, and have another for next time. The old stuff was very crusty/solid around where it wrapped closest around the pipe, and there were some plugged holes. I just took a very sharp edged screwdriver and screwed/scraped out the holes from the top side in a spiral fashion (probably 15 or so), then washed it down with some carb cleaner and compressed air. Also took that same screwdriver and scraped off any hard stuff, rewashed it down, then once they were all "clean enough" I rolled the packing up and had the kiddo handle some masking tape to hold it in place in 3 equally spaced areas (both ends and the middle), then shoved it back into to tube. I cleaned the tube prior to reassembly though, and used some hi-temp black rtv on the end side mating surface and ran it. It is now much quieter now and sounds good. [/QUOTE]
