ITEM DESCRIPTION: Yellow Aluminum (Alloy) Pull Start Assembly for 47cc 49cc 2 Stroke engines used on various Mini ATV Quad Dirt Pocket Bike Scooter etc... (see engine picture). NOTE: Look at my last picture to see the two designs available (this one is the style on the left side of the picture). I don't carry the other style (sorry). NOTE: Some versions of this engine use a plastic pull start. These are not interchangeable with the aluminum one (you must stick with the type your engine came with). NOTE: I have this style in 6 colors (Red, Green, Blue, Black, Silver Yellow). The other colors are found in other listings. NOTE: Only the first pic shows the color (the other pics are to show the design).
