Re: Starting cold engine techniques.... whats yours?
Check the choke shutters and make sure they're coming up tight against the carbs, as this will make a difference. Maybe you need to give it more throttle when starting. Another thing is too pump the bulb 'til REAL hard as this, on some models, will force fuel past the float needles and in effect prime the motor. This was virtually a mandatory starting drill for all the old inline Mercs. My 1964 1000 wouldn't start well unless it had fuel dribbling out the carbs!<br /><br />Another good trick I've heard of is to remove the choke shutters and retrofit the primer valve to older motors. Tie the discharge of the primer valve into the bleed hose assy at the side of the intake manifold. This puts fuel right into the motor and will fire it off instantly. You connect the wire which formerly hooked to the choke solenoid, to the primer valve solenoid.<br /><br />A friend of mine is having problems with his motor after rebuild (runs great but that pesky cold start!), and he's thinking about doing the primer thing. <br /><br />I imagine you could pull a primer valve off of any modern motor which used one. Of course one off an I-6 would fit perfectly!
