    Hey guys,
    Got a stihl br600 blower that I have been using personally for commercial lawns for about 4 years now. I use 89 octane ethanol free fuel running stihl's HP ultra synthetic oil at 50:1 ratio. The blower started up fine this morning but ran so rough I couldn't use it. The was no indication of problems anywhere- fuel fine, spark fine, compression fine. I finally opened up the spark plug to look at the piston and it looked fine. But what surprised me was that the cylinder sleeve around the piston was also moving up and down. I have never seen anything like this before. Is there some sort of cylinder sleeve around the piston that is suppose to do that?

    The cylinders are plated. You're not seeing what you think you're seeing

    I'm saying there's no sleeve to go up down.
    Are you in the moonshine again?

    Yeah. That's what I'm thinking too. At this point I think the blower may have a crankcase problem due to a leaking crankcase tube from the carb. It's at the dealer to find out what is really the problem. May have to consider a new blower. My last br600 went out in three three years also. Any of you guys ever used a husqvarna 570 or 580 blower? The dealer said I would like these as a replacement.

    Average life up here is about 3 years, on any blower. No where to get rid of clippings, so blowers are used on every lawn. I figure they get about 300-400 hrs a year. They run wide open all the time. Hard to complain about lifespan when you think of the usage.

    I already said there was no sleeve to go up and down!
    What I am saying (and what you alluded to) is that with the chrome plated bore, the mirror effect has produced an optical profusion, er, illusion. Magnified by the fact that a lot of people don't know what the pluck they're lookin' at.

    Moonshine????????

    Nothing wrong with moonshine as long as you don't try to sell it...or drink it with tools in your hands..
    You could probably run your mower on the good stuff....so I've been told..
