'85 R suddenly won't idle
I've owned this machine since '89, put the current 36 PJ carb on it in the early 90's. The jetting on it has been perfect all these years. I took it out for an hour long ride on the gravel roads the other day and it ran the same as it always has but wouldn't idle for the first time ever. It's been about a year since I had it out so I figured dirty pilot jet. I took it apart and cleaned all passages and jets with carb cleaner and compressed air. It looked clean inside and was stored without fuel in it. The air filter is clean. It made no difference. The only way it will idle is to crack the throttle slightly. Running the idle adjustment knob through its entire travel makes no difference either way. Is there anything other than the carb that could affect the idle like this?
