I have a MW tiller with the same GIL number, except it is an "A" model. I was given the wrong manual by Wards, so I can not help you with a manual. However, Clymer Outdoor Power has published a Rotary Tiller service manual, 3rd Edition that might help you. It covers both WW and Gilson tillers as well as other makes. Their Customer Service number is 800 262-1954. Bob D
