My 5 HP B&S engine propells a log splitter. It is a 206 cc industrial/commrcial engine. The model number is l32232; type 2l36-0l; code 84l00307; serial # K-20763l; I purchased the equipment used and would like to know what year the engine was manufactured. I believe that the type and code are some kind of clue - that is if you know how to read the numbers. Any information would be appreciated. Incidentally, the engine runs well and seems to be a well designed and constructed piece of machinery.
