    What’s your opinion on the condition of both. Good to go, or ditch them?
    Original cylinder with meteor slug. Would the scratches on piston worry you? Is the cylinder wear too much?
    Scratch on exhaust side. Could be from a carbon chunk?

    If it were me, I'd use scotchbrite on a drill in that cylinder. I have a series of holesaws that I wrap with the pads to "hone/polish" the plating after removing transfer. And the piston, as long as you can't catch a fingernail on the groove or nothing is poking out, good to go(imo).

    Prefilter for incoming air to the carb.

    I wouldn't worry about those scratches at all but that's just my opinion.

    I think you will be fine based on what I see. Although anytime I clean or polish up a cylinder I replace the rings.

    Good to see you working on the 242xp!

    So.......why don't you install that new piston and cylinder kit that you got, get the saw up and running......and then clean this one up and keep it as a spare? It took a lot of elbow grease and patience to sand/polish (with sandpaper and rotary tool) the muffler port on my 034 rebuild....but in the end it was damm worth it. Thanks huskihl for giving me the confidence to do the job. Just took my time and really took it nice and slow and didn't rush. That way I made sure I didn't over do it.

    Or you could clean it up and reinstall and see if everything goes well. What's the condition of the little nubs that hold the rings in place (prevents them from spinning)? On my 034 the piston nubs were shot so I was glad I had ordered the Meteor piston.

    Well after pulling it apart I realized the piston and cylinder were not the issue. It must’ve been a fuel issue that was causing the problem, so I replaced the fuel line and fuel filter and now I’m waiting for carb kit to show up.
    I used some oven cleaner and scotch brite to clean up the exhaust port. I’d rather have the oem cylinder on it. The piston is a fairly new meteor. I’ll keep the polish kit for a back up.

    Well you had a missing gasket for the muffler at the exhaust port if I remember correctly yah? And a lot of carbon build up there, no? Wasn't it an air leak at that joint?

    Did it start with some starting fluid sprayed in the spark plug well?

    Yes it had a broken muffler gasket and carbon buildup with chunks missing. The saw would lose power and want to die in the cut. When I pulled the muffler it appeared to me the piston was toast.
    Lots of important parts are nla for this saw including piston and cylinder. I wish Husqvarna would continue to support all the 2 series saws.

    So yeah maybe just clean up the exhaust port, get that carbon off, slap in a new gasket, and reassemble. I think that might solve your problem especially since you already replaced the fuel line and filter. Carb rebuild kit is a good idea too and if you take apart the carb and all it needed was a cleaning, put that rebuild kit with the p/c kit and keep it for the future.

    Me too….. especially since there’s so few of them around here, can’t find junkers for parts or builders.

    Yep there's 2 of 'em.

    One is missing a starter rope. I don't recall what the issues were but I did take a video of it that I have to dig up.
