It should “peel” open from bottom to top, spray some release oil in each top corner so it can soak in and gravity will play its part too, tap round the sides and top with a small (technical term) tapping hammer and try to gently prize the two sections apart from each bottom corner where the screws were located, dont be too forceful, patience will be the key [emoji106] if you do decide to use heat then do it sparingly along the whole circumference of the muffler tapping it as you go with said tapping hammer. Patience is the key [emoji106]

Try getting a big screwdriver under the front cover between the two removed front bolts, use the top edge of the oil tank as a fulcrum.....that's a pivot point! and try to lever the muffler off. It is only rust and perhaps an old gasket holding it in place!

I’ll give it a go in the morning. Although it’s been a bit windy so I might be busy!

A healthy 038 does seem to have a fair bit of compression compared to a lot of other saws. Bring it to TDC and pull through the compression. I've never thought of them as heavy but then I don't own any "modern saws" and have been using 038s for a "few" years. As recommended, pry the exhaust open from the bottom. It is in two parts and the folded lip at the top holds it together even after the top screw and the two bottom bolts are removed. Once you get the front over off you can access two further bolts that thread into the exhaust flange on the cylinder. The only gasket on this exhaust will be the one between the exhaust and cylinder. Don't get too heavy handed trying to remove the exhaust as it is possible to break the exhaust flange. I've seen the aftermath of someone doing just this.

Thanks. It’s not that heavy really. Work has an echo 620 and I thought that was quite heavy. Compared to my 550xp, but it feels solid which I like. It was my intention to use it as a cross cut ‘bucking’ saw if I can get a decent sized bar on it if it’ll pull a bigger chain. Thers a large fallen beech tree that I need to sort at some point and I’m reluctant to drag the 880 out to it. That’s bloody heavy!
