This is the engine that was almost stuck. I had to take it apart. after a fair amount of work i had the engine turning free. I had it running several times for about a half hour each time.2 cylinders had no compression. I thought it was 1 intake and 1 exhaust valve sticking. i removed the valve cover thinking maybe the springs broke. I found valves are moving freely but 2 lifters take a fair amount of force to push down all the way and are holding the valves open slightly. the lifters look nice and shinney what could be causeing this? I thought if i ran the engine they would come loose but after an hour of total run time still not going the last 1/8 of an inch.
