Well im pretty shure the low speed jets are pluged on # 1 as 3 because it's fireing good and it runs good going down the road. Ive run a hole can of sea foam through it but didn't help.Has anyone tried taking the manafold off an spraying carb cleaner in the carb? Could the cleaner get to the jet or would it just make things worse?

The slow jet forks off in two directions. One port goes to the back side of the air cut-off diaphram, and the other goes forward and comes out just behind the throttle plate. Getting them all clean is not easy, especially if it's an 80/81 where those jets don't come out. I don't thing you'll have much luck without pulling the carbs...I've have been wrong a few times in my life though....

You ain't wrong on that one though, no way to clean the jets without removing the carbs.

I sprayed carb cleaner in the slow jet hole it came out where the air diaphram gos plus in the carb, Is this right?

There are three or four holes right where the throttle butterfly closes in the venturi. They are part of the idle circuit and can be blocked. I used the inner wire of some TV coax to prick them clean.

I took the accelerator pump apart the diaphram is worn and real thin in places. What will this cause? The motor has good power going down the road, It's just not getting any gas at idle on # 1 an 3. Please help.

Basstracker,
I need to put some miles on my clattering Aspencade. I also have a 80 GL1100. I'm only 54 miles from you, and I do not mind coming down and giving you a hand. I'm pretty sure between the both of us, that we can either get gas to the carbs, or really screw them up, LOL. It will have to be after the 5th thru the 8th ofSeptember before I can afford to come down, but no charge whatsoever.
Try this.Run the engine for 10 minutes to warm it up. Turn the Motor off. Turm the idle jet (with the 8mm bolts) screws in until it barely touches, then, turn the #1 cylinder 1 + 1/2 turns out. Do the #2 and 4 like this also. You can then adjust any "Popping" you hear by turning the adjusting sctrews out 1/2 turn at a time. #3 is the base line for setting the carbs with a nanometer, but you can get gas to the cylinders, but not as close as you can without a nanometer.
Good Luck,
David

Well i just thought i was through. When it's idling it's hitting on all 4, When your going down the road if you give it just a little gas it runs good, give a little more gas and it's like you pulled two plugs, give a little more gas and it runs fine. Please help.

Did you clean the air cutout valves and the little air cutout cover with that tiny little hole in it, and all the other small curuits?

Another thing you might want to do is check to see if your timing is advancing.

There was a rust color in the bowls.

Check your tank for rust. Small rust particles will pass through the fuel filter, and coagulate on the little screens under the float valve seat. If you have a rust problem, it's best to take it to a radiator shop and have them derust and seal it. There are ways to clean the tank in place, but results are spotty, and you still have to seal it or the rust comes back. Hard to seal effectively without taking it out...

What? I sure hope you don't go help him with his carbs. :shock:
