150cc Scooter Won't Start. Please Help!

[panda]

First time poster. My Flyscooter Il Bello 150cc isn't starting with the electric starter. I used a charger and made sure the battery is charged up. All the lights turn on fine and the horn blasts at full power. However, upon using the electric starter, all it does is click (and if I hold it down I can hear a slight screeching noise). The lights stay on through the clicking, but its like the starter isn't turning over and engaging. Just clicking.

This scooter was always hard to start up when cold, but the starter would always turn over no problem. The last couple of times I started up the scooter before the clicking problem the starter sounded like it was churning slowly at first before giving a strong start.

Unfortunately I have no ammeter or other way to measure what's going on electrically at the starter itself, but I suspect the starter is simply bad. I found this on amazon (link below), and I'm not sure whether its compatible or if the starter is the problem, so that's why I'm here for your help. Additionally, the kickstarter doesn't really work and never has (even before this problem with the starter), so I can't test the engine that way. Thanks in advance!
