HumanoidThe23rd Posted March 28, 2012 Report Share Posted March 28, 2012 Hey Guys. So I finally got my 720 back on the road after a year and a half. Its running like a champ with the new Z24 I put in it. Now Im having an issue with high idle speed. I believe it has something to do with the auto-choke or the choke pull-off. I sprayed it down with carb & choke cleaner but it didnt do anything. Sometimes it idles right but most of the time it idles as if the choke is not disengaged. Anyone have any suggestions for me? Thanks In Advanced. Quote Link to comment
datzenmike Posted March 28, 2012 Report Share Posted March 28, 2012 Look down the carb once the motor is warm. The choke plate should be vertical or fully open. If not perhaps there is no voltage to the choke heater when running. Check the wire on the choke heater with motor running. (it's actually a Blue wire under the black covering) If no voltage check your battery voltage when running (14v or over) as the heater relay needs alternator output to work (motor running) .

HumanoidThe23rd Posted March 28, 2012 Author Report Share Posted March 28, 2012 Thanks. I know my alternator isn't charging to the fullest. Could that be a cause of the high idle? Quote Link to comment
datzenmike Posted March 28, 2012 Report Share Posted March 28, 2012 Yes. The relay needs full charge voltage from the alternator to stay on and supply the heater. This relay is that way so that if the motor should stall while you are inside on a cold day having another coffee, the choke won't warm up and turn off, making the restart very difficult. If you aren't too worried about this just jumper a wire from the idle cut solenoid (red wire) just to the right. It is only on when the key is in the on position so this works perfectly. Either way that alternator needs to be looked at. Quote Link to comment

HumanoidThe23rd Posted April 3, 2012 Author Report Share Posted April 3, 2012 So I realized what was happening with the high idle. I hadnt torqued down the connections on the back of the alternator thats why I wasnt getting a full charge off of it. It idles and runs perfectly now! Thanks for the help you guys. Also Poor-Man-720 If you still wanna hook it up with your old alternator for a couple double cheese burgers Im still down to do that. lol Let me know deww. Quote Link to comment
