How to replace a broken electric start button?

[Sjwelsh1]

I have an Agility 50 that has a broken electric start button and is pushed back into the handle.  I am looking for specific direction on how to replace it unless it requires a dealer to fix it!  Would appreciate any help doesn't look like it should be too hard.
Thanks for any guidance!

You HAVE to replace the throttle assembly. I broke a few, and replaced a few that corroded too far for repair.
You DO have to remove the throttle cable from the carb end to gain slack to replace the part but it should take about 1.5 - 2 hrs for a first time.
