My carb, a dellorto phbh seems to have developed an intermittent airlock.
The engine's been cutting out as if running out of petrol. While checking the fuel flow I accidentally discovered that occasionally fuel will not flow from the tank down the pipe. If I remove the pipe from the spigot at the banjo bolt, the fuel flows freely. I put it back on - it stops. If I tap the carb , bubbles form and it slowly flows again
The carb's been cleaned with carb cleaner and blown through with compressed air and the float seems to be fine but the problem still persists.
Has anyone got any suggestions ?
Cheers
Tony.
