Here you have an owner's manual for the 1979 AMF Model 125 Roadmaster moped. Also included is the McCulloch BHE 900 engine manual (photo 3). The information in these would probably apply to other years as well. The engine on this model was mounted above the rear wheel and enclosed in a large plastic housing. There should be enough data in these two to have you blazing along like a greased frog in no time!
The AMF Moped Owner's Manual is 26 pages long. The McCulloch BHE 900 Moped Engine Owner's Manual is 10 pages long, and includes in it's middle a 3 page Illustrated Parts List, for a total of 39 numbered pages. The 3 Illustrated Parts List carries a date of December 1978. The Moped Owner's Manual has a date of 4/5/79 on it's last page.
Each is individually comb bound with a sturdy 10mil clear plastic cover both front and back.
