Randy that's part of the 33-42cc Poulan series that includes the older non-stratto Wild Things. This particular saw is a non-AV version. The EPA sticker on the 'boot plate' under the rear handle will have the true displacement. Will say "engine family 42cc" or something similar. Poulan (and therefore Craftsman) often will put a 'downgraded' displacement on the recoil cover sticker when they're meeting a lower price point............................when in fact the saw is actually 40 or 42cc.
With the case it's for sure worth $15, especially if the P/C are in good shape. The piston on those is chromed, with a bare aluminum cylinder bore (like a 3400). Looking in the port will show a bright, shiny piston............even if the cylinder is scored. Most of the time people use those once or twice, and then stick them in the garage with a tank full of fuel. The carb diaphragms, and the fuel lines and purge bulb are often shot from sitting (and that purge bulb does look wasted).......and they pull and pull and pull until they give up on it. $15 in parts and they're back up and running....
I went thru seven of that family and made four runners out of them. They were labeled from 33cc to 42cc and there was no difference in the cylinders/pistons that I could find. Toss 'em if the comp. is below 140.
My backup/rescue saw is an engine from a 42cc antivibe chassis in a 40cc solid chassis. Use the purge bulb and choke right and it starts first or second pull.
I removed all the stickers for oneryness.:msp_tongue:
