[FONT=Helvetica, Arial, sans-serif]hello![/FONT]
[FONT=Helvetica, Arial, sans-serif]i think i have a problem with my auto start assembly prime/solenoid? [/FONT][FONT=Helvetica, Arial, sans-serif]is it just supposed to push the piston onto the carburetor linkage when holding and turning the key?[/FONT]
[FONT=Helvetica, Arial, sans-serif]i'm guessing it is broken..(cause i dont know what or how its supposed to work, except pushing the piston onto the linkage) when i connect it to 12 volt nothing happens, but when i check with multi-meter the current is going through.
could the problem be in my key switch ?
it looks just like any other magnet-valve but 100 times more expensive
i just bought the motor so it has never worked for me,[/FONT] [FONT=Helvetica, Arial, sans-serif]but the part will set me back around 220$ so i'll rather try everything else before buying it[/FONT]

the protection cover is lost and there is supposed to be a little screw at the botttom

On 2 strokers, and using Merc/Quicksilver 2000 and probably 3000 control boxes (2000 have the fast idle lever at the top rear of the box, 3000 have the big black plastic disconnect knob for throttle only operation) when you push in on the key you send 12v to a fuel enrichment/primer solenoid which allows fuel to run directly into the combustion chamber, through a special port in the carbs on some engines, or directly into the intake manifold.

Go to your fuel "priming" hootus and disconnect the input connector, checking for 12v when you turn the key to ON and push in on the key.....may work without the key being in the ON position. If you get 12v when you push in and no priming fuel then your primer is bad. If not chase the wiring to and including the switch.
