Having trouble with idle solenoid in my stock Aisan carb. Just finished the rebuild kit and was having trouble with idle and figured it was the solenoid. It bench tested fine, but doesn't work once installed on the carb. It has 12v going to it, and I ran a ground straight to the battery and can't get it to work. Take it off the carb, it works, put it on it doesn't. This is the last thing stopping me from being able to drive my 40 for the first time since aquiring it. What do I need to do?
