[Impaired]

I have a benelli 150xt, the one in my signature, and I'm having extreme difficulty finding parts for this scooter.

I need a new carburetor, a new air filter and intake manifold.

It's a dual vacuum intake manifold, I bought one but it's way too short and it doesn't line up with the bolts to bolt it on (too small) it was advertised for 150cc scooter so I'm confused.

I have no idea what kinda carb to buy.

I cannot find a replacement air filter, what should I do about this?

Any help would be greatly appreciated, i want to order the new carb ASAP so quick replies would getamazing on the carb issue.
