If it's on loose gravel it will spin out, but on pavement it just bogs down and stops.

So I've done some research, this did not come with a torque converter, but has a centrifugal clutch so no adjustment possible.

The drive gear is 10 teeth and the driven is 44. It also has 15x6-6 rear turf tires. If I buy smaller more aggressive tires will this help enough to climb? Or do I need a new drive gear also. We're are talking about a 10-15% grade .
Smaller tyres will definitely help, but getting a larger axle sprocket would be better. Get a 60T
