I recently purchased an old Briggs & Stratton engine for my 21st Anniversary Greenfield ride-on. The engine does not have an engine cover, so I don’t have the engine details to determine the correct engine cover. I want to use a pull starter, so the opening in the engine cover needs to be concentric to the shaft. The flywheel suggests the engine is a 25 series i.e. 10HP, 10.5HP, or 11HP. I tried an engine cover off a 1986 11HP 253707 0160-02 (red), but it’s too small and won’t go over the perimeter fittings. I tried the following engine covers, but they all needed front spacers, hit the air filter, and the shaft was 3-5mm off centre from the opening: 1993 10.5HP 28B707 0115-01 (black). 1999 11.5HP 28D707 1126-E1 (red). 1987 12HP 281707 0148-01 (red). 1993 12.5HP 286707 4030-01 (dark red). 1994 12.5HP 289707 0114-02 (dark red). 1993 14HP 287707 0153-01 (dark red). Can anyone identify the engine from the photos, so I can buy an engine cover that will fit the engine?
