Piaggio Typhoon Carb problems
What i have here is a piaggio typhoon 50cc 2 stroke, it has a 19mm dell’orto phvb carbarateur
With the original piaggio filterbox, together with a malossi red sponge filter inside, the scooter does not do a thing, unless i spray brake cleaner into the filter’s intake
When i remove the filter completely, so the carb’s intake is open air, the scooter does work when i hover my hand over it a bit and cover it a little every once in a while, i can feel my hand getting wet from the fuel while doing that. It does not want to stay running and completely bogs down once i remove my hand

(At the start the throttle cable wasn’t in correctly)
Now when i put a little cloth over the open air intake of the carb, and attach it with elastic bands:

It suddenly runs completely fine, no issues. Maybe a tiny bit unstable as you’re usually not meant to use a cloth as an air filter, but it doesnt stall or just bog down for no reason at all, video here:

Does anyone know why the f my scooter is acting so damn weird? I already tried installing a bigger jet, originally it’s 72, went up to 84, did not change anything to the open or filtered setups, just made the cloth setup run a bit rich
I did also remove the restrictor plate before the membrane, but that did not change a thing, only became more powerful when using the cloth
I am genuinely confused by this and just want to get to driving this thing
By the way, i am new to 2 stroke scooters, first one i have ever owned, did have 4 4 strokes in my past, all of which i have bougt broken doen, and fixed myself, so i do have some experiences with engines, just not specifically 2 strokes
