I have this scooter trying to fix for a friend. It will run for about a minute slow down and stall. The spark plug gets all sooty and black looks like a real rich mixture. Here is what I have done hasnt helped.
1: new plug 2: new petcock thought the old was leaking into vacuum line. 3: cleaned carb very well float works fine. 4: auto choke works on the bench with 12 volts dc 5: according to what I read the choke in the bike has 18volts ac and that is suppose to be good enough? no dc to it 6: all stock jetting
Am going nuts any and all help much appreciated!!!!!!

Check the air filter and air box. Rich is black and wet. Black and sooty is usually an indication of air being choked off to the carburetor.
