My MTD won't start. Please help.

[Bikebuilder63]

Okay, so about three years ago I shut down my MYD lawn meet because the front axle was cracking. It ran just fine, however, I had to stick a screwdriver on in the solenoid area in order to start it. I forgot what/how I did it so I decided just to fix it. So I replace the solenoid expecting that to fix it. I put a brand new 12 volt solenoid on it and it will not even try and start. I know the engin is good because three years ago, it started and hasn't been touched since.

The model number is:136B560B000
The serial number is: 2E206G50184

Some one please help me out. I've had the betters charging all day and I just tried to start it and still nothing happened.

Thanks in advance to whomever helps
