Well that all makes sense and thanks so much for the explanation. I was wondering what that spring loaded contraption was. With the motor the way it sits, I cannot hold the throttle against the stop or it will stall out. I have the throttle cable maxed out to keep it at a higher idle to start up, but at least have it set up where it will idle down to 700-900 in gear, or about 900-1100 in neutral.
The quick start feature all makes sense with the pulsating now too.
On the topic of engine temperature, what should I do to help this motor warm up? I pulled the thermostat already and you sure are right. A lot of stuff seemingly going on there. Do these thermostats work similarly to the older style ones…just open up at 143°? This one appears closed, but than again these 40hp and above motors have much simpler cooling systems/water routing. I can see why they pump water like a fire hose because they are certainly more forgiving in terms of preventing clogs throughout the water path (basically just into the giant exhaust bypass cover, around the cylinders, through the T-stat orifice, than out the cylinder head and down through the exhaust housing…and not really any small areas for things to get clogged up in).
