Been yard and farming for years but I'm stumped on this problem. My John Deere LA130 has a starting problem, especially when cold or not run for a few hours. I changed the starter with new and starter relay. New 350 cca battery and checked all cables. If I try to start it it only turns about 1/4 turn and stops. Seems to stop in the same spot all the time it does this, but will start great if it stops in other area of rotation. J.D. dealers is stumped also. Appreciate any suggestion you have. Thanks.
