Just picked up a new to me MS290 that has had the cylinder replaced. Peering under the plastic I noticed it has a decompression port plugged off, so I am wondering if anyone has seen cylinders other than the 49mm/MS390 jug that had a compression relief valve?
If I were really curious I'd pull off the muffler and measure the bore, however the saw seems to run pretty good at the moment so it is more of a curiosity thing than anything else, but wondered if there might be a less intrusive way of figuring out what is on it.
Thanks!
