I have a 220 with a seat that is hinged on the right. Today I picked up a 250 but the seat seems to be permanently attached. Is it suppose to hinge like the 220? Thanks.
The 220 was hinged from one side as you said. The 250 was attached with 2 aluminum angle rails. The seat slid in from the back and the rails had notches that caught under the frame below the carb door.
