So would it be a noticeable step up from the 55 rancher? And would it be a good saw to port?
nope, it's totally different compared to 55.
More light faster better balance, 4,7kg without bar&chain, 42cc, 10k rpm, 15,5k rpm wot, pure limbing machine. Aint any 42cc out there who is as good as one 242 when it goes to limbing work.
It's starting to be extremely difficult to get spare parts to them now. Other then a healthy compression it's important that crank bearing is in good condition, one of the crank bearing is NLA.
242 was build on the 133 crankcase.
133,234,238,242 have closed port cylinder while 42 and 246 is open port cylinder.
I've seen top shape 242 sold on ebay for 250-300€, 100€+ is what you have to pay for an project. I dont buy on ebay, prices are jacked up to much.
Local in Norway I get them from 50-100$
I have 3×42 and 2×242, they are all keepers!
