My 1995 Nitro 170-DC Tracker with a Mercury Mariner Tracker Pro Series 60 engine has a key/choke ignition switch which activates the choke when I push-in while the key is in the Start or Run position. I have no idea how this works and would appreciate some clarification.
I assume the engine uses electronic fuel injection rather than having a carburetor with a choke plate that closes. I've heard several suggestions for starting the engine:
(1) push in the key and hold to choke for 5 seconds before you crank the engine.
(2) crank the engine while holding in the choke till it fires.
(3) turn the key to the on position, bump the choke 5 times, turn the key and crank the motor while bumping the choke 2-3 more times.
(4) if the engine sputters after you let go of the choke, punch it in again until it smoothes out.
These all sound reasonable but I am open to suggestions for the best method to start the engine. The primary question here is: do I push and hold for 5 seconds or bump it five times? When you hold the key in does gas squirt continuously or do you get one squirt each time you push in the key? Thanks for any clarification you can give me.
