Re: 1985 chevy 1500 won't idle

Use a good carb cleaner first. Then, fix the choke and adjust. After all that, then change the idle. First set the timing, then idle. Over time, these trucks do need minor ingition adjustments. You may need a simple 1/2 turn on the idle screw. Over time, it does wear down from the carb lever hitting the screw end.
