There are a few models it could be, and a couple of engines, so we'll need more information. If you could find us a serial number, we can tell you what you need to know. There are 3 places to look, depending on which model it is. It could be on the left side of the engine block, the right hand side of the transmission in front of the right brake housing, or on the lower part of the dash.

If you can't find a serial tag, look for some part number that are cast into some of the larger parts, and post them, it will help narrow it down.
