Hi all! I just joined here today. I picked up a Cub 127 Hydro I think a 67-70 model. Got it running and had to free up the plungers in the check valves last week. All was going fine after some WD -40 and cleaning them off. That was last Sunday. It's been in the garage all week. It started today easily and after I let the engine warm up I tried to back out of the garage, no movement, nothing forward either. This thing sat for a few years in a barn before I got it. I figured I'd change the hydro fluid and filter since I was having issues. I noticed the old hydro fluid had tons of tiny air bubbles in it when I drained it. I put in new fluid and filter and same result. When it is running both check valves are up but there no pressure behind them. Not sure if there should be. Some one told me to purge the line for air or it may be the valves. Any thoughts, opinions, advice would be greatly appreciated. Thanks in advance!
