Well I thought that I had a bad solenoid on my older (At least 15 years old) MTD and it was the starter. There is a green wire and red wire on the solenoid that I crossed when I put the solenoid on and the motor had alot of smoke (electrical) coming out of it. Now I can get the motor to crank but no spark. What do I have to replace now so I can get this to run. Thanks for the help.
