I have a 1957 Evinrude fastwin.I have rebuilt the carb,new plugs&wires,new coils,points,condenser. The motor seems to run best at high speed when the fast jet is almost closed(just cracked ) or leaned out. As I slow down I must richen the fast idle to transition back to an Idle. All this takes place with the slow jet opened at 1 turn.<br /> Does this make sense? Will it burn the motor up to run it so lean. What would the problem be?<br />Also this motor is fairly cold blooded and sensitive to starting procedure. example to start motor. 1. pump air into tank,no choke,turn throttle to start. 2.pull cord 2-3 times. 3. pull choke then pull cord to start & die. 4.push choke in, pull cord, motor starts and runs. Is this typical of this motor. Any suggestions? Thanks..
