I moved the hydraulic control lever again tonite as I was taking the tunnel cover off to look at the clutch and believe it or not the motor free'd up! I tried this before with no luck, but now I can spin the motor. Does this mean I have to service the hydraulic control or can I assume that I'm good to go. I got some gaskets coming in the mail and an intake from a 185 to accommodate the new zenith carb. Fingers crossed this weekend maybe I can fire this thing up and take a cruise. If successful I am going to pull the head again. There was a ton of carbon build up on the valve and pistons. I tried to scape away as much as I could but there is still a lot left. One thing that has me concerned is that the carbon build up on 2 of the cylinders was jet black but the other 2 were a whitish brown color.

Also when I did have it briefly running the hydraulics worked fine with a deck mounted. The deck went up and down several times without any problems

A healthy dose of SEAFOAM in the fuel and oil will help clean the engine. You can also spray it into the air intake. Do a search on the regular farmall cub forum. Someone posted on this subject not too many weeks ago.

The lever to the hydraulic control valve has 3 positions. Pulled to the rear to raise the deck and should spring back to center when released. The forward position should snap into a detent and stay forward. This is the float position and lets the cylinder push fluid back into the system if it hits an obstruction. The center and float positions should not build pressure. If the lever stays in the rear lift position it will build pressure to the cylinder. If the lever was in the center or forward position and it built pressue something is wrong with the selector valve. Assuming no 3 point hitch on the tractor. Be sure to check the fluid level of the transaxle. That is the fluid resivoir for the hydrsulics.

Just want to say thanks again to everyone for helping me out. Hopefully when I get to know this model more I can return the favor to someone new and pass on all the info I learned. Great site ya got here

Pull the spark plugs and verify gas didn't hydro lock it. If gas comes out of the cylinder when cranking that was it. Remove plugs from wires to prevent a fire. I had this happen on my Cub 1812. Now I always turn the fuel shutoff OFF.
