WILL NOT IDLE

[woody goss]

MY GL1100 HAS SUDDENLY DEVELOPED AN AVERSION TO RUNNING UNDER 3000 RPM. DROVE TO WORK YESTERDAY EVERYTHING WAS FINE. WHEN I STARTED IT TO COME HOME IT
IMMEDIATLY DIED. IT DONE THIS SEVERAL TIMES TILL I FOUND THAT BY KEEPING IT REVED IT WOULD STAY RUNNING. IT HAS 79000 MILES AND HAD BEEN RUNNING FINE SINCE I REPLACED THE WATER PUMP, AND INSTALLED NEW BELTS AT THE SAME TIME. WOULD APPRECIATE ANY CLUES TO THIS NEW PROBLEM.. THANKS. WOODY GOSS

Strange, ran fine to work but wouldnt run below 3k rpm after work.

My first thought is idle circuits in the carbs but showing up sudden like is odd.

Does it feel like it's firing on all 4 cylinders at and above 3k rpm?

I would first check for spark on all 4 then good fuel flow from the pump.
If you have spark on all 4 at cranking speed and it DOES start, the problem isnt in the ignition, has to be fuel related.
If you dont have a vacuum leak that suddenly happened like from a cruise control vacuum line coming off or something similar, my money is on the idle jet in one or more carbs became plugged.

RE: FIRING ON ALL 4, YES PLENTY OF POWER, GUESS I SHOULD TELL YOU I HAVE A CYCLE INNOVATION
CARB CONVERSION, AM RUNNING A SINGLE BARREL HOLLY CARB. CHECKED VACUUM LINE, OK. CHECKED
FUEL FLOW, AND JUST CHANGED FILTER AFTER READING POST. SAME RESULT. NEIGHBOR SAW ME WORKING ON IT AND SUGGESTED IT MIGHT BE ALTERNATOR.CALLED LOCAL HONDA SHOP, THEY SAID NO ONE THEREKNEW ANYTHING ABOUT ANTIQUES,(HA HA) I FIGURE THERE HAS TO BE SOMEONE IN JACKSONVILLE WHO WILL WORK ON IT IF I CAN JUST FIND THEM, I CAN DO A LOT, BUT AT 71 ITS HARD TO GET UP AND DOWN ANYMORE.

Even easier with a single carb to diagnose since we're dealing with just one idle, primary, and secondary jet.
I bet it's a plugged idle jet. Some shmegma (technical term) got in there.
