Hey folks! First of all..... Thanks to all for the advice, clues and guidance! I got the valves a few weeks back..... Just found the time to do the labor a few days ago. Got her back together, turned the key..... And.... She purrs like a kitten! Runs very good! Now i have a new issue, though! When i engage the pto..... The motor dies. I can drive this thing a hundred miles and she runs smooth..... But every time i engage the pto..... She dies. What did i screw up?
