140L compression
I have a 140 L that I bought used and had serviced about 2 years ago by YS and it has been sitting in a closet since.
Just got it out to put in a plane and found it has very little compression. Does that seem normal?
I will try to start it this weekend on the bench which will be my first time to run it.
thanks in advance

RE: 140L compression
Sounds like the lifters are gummed up. Pour some raw fuel down the pushrod tubes and let it set for a while. Then hold pressure on the pushrod side of the rocker while spinning the crank. They should free up. The other thing would be to send it in for a going over.
