How do you compress the front v-belt drive centrifugal drive clutch assembly on a scooter?

I'm attempting to replace the belt on my 49cc scooter. I'm not sure how to compress the front v-belt drive centrifugal drive clutch assembly. I already have the drive belt cover off.

I've compressed the rear clutch assembly, managed to roll the replacement v-drive belt on the scooter. But because the FRONT centrifugal drive v-belt clutch assembly will not expand, the scooter is in the wide open throttle position and my scooter will not start now.

I need to know how to open the front clutch assembly. Any information you can offer would be highly appreciated. Thank you and I'm looking forward to hearing from you very soon.

My scooter is my only source of travel and I need it badly. Thank you again.

The front assembly as the name states is a centrifugal clutch meaning as it turns it will move on its own. It should have no bearing on how your scooter starts because as soon as it does it spins into place.
If the belt snapped the rollers may be worn or the plate that holds the rollers may have warped and that could cause it to become stuck.
Take a pneumatic impact wrench and take the front nut off. slide the plastic flywheel off and the first metal plate. Then slide off the rear assembly.
Inside the rear assembly is a set of 6 rollers that fit into the grooves and a plate that holds them into position. if there is a flat place on the grooves or in your case they arent seated they need to be replaced.
Make sure you have 3 plastic spacers that sit in the grooves on the rear plate that fit around the pegs on the main plate.
Once it is all seated correctly slide them back onto the peg, it should slide fairly easily.
then get your belt into position and replace the front assembly.
If it still doesnt start check your Valves

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.
