Before i had my 250 rebuilt, it had about 70k miles and it was very tired. Using the method that eric described is what worked best for me. I would pump the gas twice and press down a bit on the gas and crank it and it never took more than two turns before it started, unless it was dormant for months. Always as fast or faster than a brand new car, hopefully it will still be that easy with the engine all fresh now =)
