I bought a Wisconson engine from a estate sale last week and was wondering if anyone can help me find out age and horsepower ? This is mounted with a lever that engages and disengages a clutch but no one there knew what is was used for. I have not had time to fool with it yet but was stored inside and looks in great shape. These are the numbers I found on it, AHH 1149475, 3 5/8 X 4, AND 48077. Thank you all for any info you can offer !
