Modern Vespa

Ok removed carb whilst bike is a non runner ATM.
Managed to finally open float bowl after getting quality screwdriver. No stripping which I'm happy about but idiot me did not record the screw settings for stock.
Any advice
Bike is piaggio x8 125cc 2005
I believe carb is CVK 30mm
Not sure if exact has all it has is CVK on it and a serial number

Hi buddy,
stock afr screw, 1 1/2 -1 /2/3 turns out from soft seat, then adjust big running screw until engine idles low and smooth.
cheers Andy.

Once again Andy thank you, hopefully get motor running back after Xmas.
Also found some sponge where diaphragm is , take it this isn't normal

Hi sutty,
The sponge in the diaphram is the air filter from the .cv intake balance port that has biodegraded and been sucked in.
You will need to replace it or shit will get sucked in and make short work of grinding the diaphragm body and seal to bits.
I use a piece of stocking, others use a piece of air filter, just make sure it's free flowing or your plunger will not rise and you will run rich and bog down.
Cheers Andy

Andy could you help us out with a photo , looked online.(does the foam go down there?
On my carb there is a yellow cap but the hole is open on the side(see photo)

hi sutty,
in the first picture you have a round piece of yellow plastic, the filter lives in there and the plastic retains it.
cheers Andy.
