Re: what is it??
The little tire valve thingy....you can use that to inject engine tuner and fog into the engine. BRP engine tuner and fog cans have hoses attached with screw on connections to fit the valve on the engine. Makes it easy.<br /><br />The fuel primer solenoid takes the place of the choke plate. Now, when you push in on the key, the solenoid is activated and opens a little valve inside it. This lets fuel shoot straight into the reed behind the carb. Take a closer look and there will be a small hose running to each carb from the primer solenoid.
