I just had my motor profesionally rebuilt. The builder suggested that I would be able to drop it in and go.....I was able to install and start it, but for some reason I believe that the motor lost it's spark, I am unable to get it to start now. What do you suggest I do to trouble shoot the problem and ensure that the motor is producing spark ?
