Engine is installed in a Cub Cadet garden tractor Model 2086

Customer Question

Engine is installed in a Cub Cadet garden tractor Model 2086 purchased new in mid 1990s. Would not start today. Backfires through carburetor when cranking. Removed both valve covers, rockers begin to move when cranking but stop moving after one or two revolutions. Am looking for exploded engine diagram or trouble shooting manual. I don't know if engine has timing belt, gears or chain but my guess is the trouble is in that system. Thanks, ***** *****
JA: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?
Customer: Fuel is in tank, and good spark at spark plugs when cranking.
JA: Do you plan on doing the work yourself?
Customer: Yes,. Retired ASE mechanic.
JA: Anything else we should know to help you best?
Customer: Source of troubleshooting manual and exploded engine diagram.
