A friend bought a theft recovery from auction.<br />We think its a 20hp but no way to tell.<br />To obtain parts he'll need some info. Does anyone know if there is info on the block? The serial tag is chiselled off and the other side is grinded.<br />If anyone has any clues as to year please help.<br />It says 100:1 at the fuel input. Have they always used 100:1?
