Vacuum or manual fuel cock?
Can't get my scooter to run at all beyond idle. Both jets and carb is spot on. It pulls enough vacuum at idle to open the cock, and toy get a few seconds of full throttle action before it bogs and returns to idle.
Suspect either fuel cock failing or dodgy auto choke. Or just some really persistent dirt in there! Already dropped and cleaned the tank thoroughly. Auto choke gets hot after 5-7 minutes and seems to move but not sure it's got enough beef to move the carb pin.
Also changed plug back to what it should be, a cooler plug but also went iridium, because iridium. Will try old plug again to eliminate that, though 100% feels like regular fuel starvation.
