I got the saw off craigslist and am going thru it to either keep or sell, checked the piston thru the exhaust and saw it was aftermarket (large arrow pointing to exhaust) so I took the cylinder off...the transfer windows looked a little strange like someone had ported them, as it turn outs someone had the cylinder bored out to 52mm and used a 046 piston. Looks to me like it was re-plated after that. Obviously less metal on the bridges between the transfer windows, decent job with chamfer.
Anybody try this before? How does it compare in performance to the usual hybrid when using a stock 046/460 jug? It certainly sounded stout when idling and accelerated good but I didn't cut with it yet.
99% sure the cylinder is OEM and it says 50zn... at the base and 1128 at the top, though doesn't say Stihl at the top like they usually do. Its a 2000 model year so late model 044 with slant fin no decomp.
Right now plan is to vac/pressure test and put back with an extra 046 Meteor piston I have lying around and go cutting
