Straight from the Service Manual:
If gasohol is used with any regularity, Johnson and Evinrude recommend the carb jets be changed to provide a richer mixture to maintain good performance and prevent possible engine damage. See dealer for recommended rejetting according to your needs.
Being that 10% ethanol is in all the gas I use, what jets should be installed? How can I tell whats in there currently?
I ask in particular because I've been struggling with the motor dying when in idle. I've gone through the carbs, fixed an air leak in the fuel lines, found the timing advance not returning to the stop at idle, adjusted cable to fix.
Now the motor starts fine, fast idles on its own after a few bumps of the choke to get warmed up. I bring the throttle to neutral and bump in gear when the tach reads below a grand, and idles fine in forward around 1200. If i bring the throttle to neutral after starting it dies when RPM go below 800. I noticed when in forward idle the timing arm is about 1/4 inch off the stop. Should I adjust the stop to be in this location? So timing remains at that setting when in neutral.
I want this motor to idle under a grand so I can shift into gear w/o compromising the LU. So far the only way I've found is to be quick shifting into gear from fast idle. I recently bought a timing light, have yet to test idle timing, what should it be @???
