Wizard TILLER model# GIS 6790 486. Has Monkey wards 2 HP engine 60102 0391-02 78050 301 stamped on front recoil housing. Probably B&S. Given to me maybe 20 years ago. Looks like engine is replacement. Starts easily. Smokes oil. Any info on either appreciated. Recoil starter and rope has always been a problem.
