The carburetor is a Bocar 1 throat tsuro that says a mechanic the other says is a mouthful 1 throat of nisan 1600 truck I have a doubt about this valve the truth is that I have taken my car with 3 mechanics and everyone tells me a different thing - The first mechanic says that the valve is placed and pressed to the stop and connected to the current. - The second mechanic says that the valve is calibrated or adjusted does not get to the top as the first one tells me and I checked it on when the car was heard very fast and when moving the car paired and leveled it also adjusting the gasoline and air. The valve was glued with a plastic droplet so that it would not move due to vibrations and lose the setting. - and the third one tells me that it doesn't matter if I have it or not connected to power but if it is important that the part is working or not. The three mechanics explained to me that it works with the low speed and what it does is that the car does not turn off and regulates the passage of gasoline that is a kind of economizer of gasoline. in down. My question is how the valve is placed correctly fits the stop, is calibrated by turning and listening to the engine which is the correct position or it simply does not matter how you put it. I hope someone gives me a solution or advice. and some page on how to adjust and carbure the carburetors correctly. Thank you.

The solenoid solenoid valves are tightened by hand. It is the low supplier, next to the throttle, with which the minimum speed is regulated. In the picture he has an o'ring that is the one that seals. When the solenoid valve is energized, it passes the fuel to the low spout and from it to the throat.
