Hello again
,
On my Piaggio Typhoon 2013 4t 4v, i always have problem with the carburetor since i buy 2 mounths ago!
The carburetor is a Keihin NCV 20mm on this scooter with Pilot jet #35 and main jet #72. Last weekend i find the electric choke never work, the wire was cut at 2 places!!!
Before i repare the choke, it was easier to have a good idle, but mixture screw was at 1\4 open!
Now the choke work but carb is realy hard to adjust the idle, poor performance and always stumble...?
Carburetor is clean, the mixture screw is open at over 3 turns ...
I have a other Keihin carburetor here, is not a 20mm but a 18mm!
I want try the 18mm in the scooter!?
If i replace the 20mm for the 18mm did i tranfer the original pilot and main jet i have in my 20mm carburetor???
Is it dangerous for the motor, it's a 4 valve motor!
Thank's!
