Thanks Thanks Thanks info hun , the engine revs up to to slightly. Now I have a bog issue. At half speed the engine struggles to get to fast idle. There is a solenoid on the atmospheric side of the vaporizer. With the connected to vaccum it bogs but with vaccum disconnected it doesn't bog and revs fine. The solenoid operates with engine started. Any idea what this solenoid is there for and why the engine runs well with it disconnected? I I no have a laptop.
