Attempting to drain the counter balance oil but a few ounces of green fluid came out. The plug is on the bottom just forward of the starter. It’s a 10mm plug with a Phillips slot. Angled about a 45 degrees compared to the floor. After closer inspection it appear to below the output shaft to the primary clutch. I think the counter balance oil drain plug is a few inches closer to the centerline. Any ideas on what and where to fill the green fluid from?
