Today I got my Coupe back together after removing, literally, two gallons of rust flakes from the gas tank and cleaning the entire fuel system, carburetor included. A quick plug here for the Bill Hirsch gas tank treatment per Bill's recommendation - seems to be working great so far.
I'd like to know if anyone has any tips or knows the "best way" to set the idle speed. My Coupe idles high, and the lowest I can get it set at without stalling is about 2000 rpm. What it the best procedure for setting the idle air jet and throttle stop adjustment? I've looked at the owner's manual instructions but if someone could share their experiences that would be helpful.
Setting the Idle Speed
Re: Setting the Idle Speed
Elias;
On your carb, take it off and pull it completely apart, clean everything, including all the jets that seem to be frozen in the casting. Use compressed air to clean everything and using a very small wire (I like a single thread of steel wire from old housing wires) Spray carb cleaner every where and using compressed air blow into every opening.
Yes, pull the needle valve and make sure the spring loaded end is operating. And clean the casting there too. Then put everything back together. If the O rings are hard and not sealing, new ones are available through your local Motor cycle shop (not Harley) K&L GL1000 1975 Carb Repair kit #18-2907, it has a needle valve but it's not usable for the Honda 600 carb.
On the distributor seal that seems to be leaking; take the advancer assembly out and using a flash light look to see if the lip on the seal was pulled over when the cam was installed. You can move it back in place using the rounded edge of a scribe (don't try and use the sharp end).

Re: Setting the Idle Speed
Also make sure the electric idle solenoid is working.

I thought the solenoid shut off fuel after the key is turned off.

Re: Setting the Idle Speed
The fuel solenoid does shut off fuel to idle circuit when key is off. But needs to activate when key is on or it wont idle. It is easy to check, take the screw out that holds it to carb and remove it leaving wires connected, turn key on and make sure its piston/needle retracts.

Re: Setting the Idle Speed
Brad, thanks for the solenoid advice - I checked it and it works fine, even making a satisfying "click" when it retracts. So I gave in a took the carburetor apart. I was especially intrigued by the very tiny screen near the needle valve that I saw in my parts diagram. This screen had some chunks of dirt and debris in it, so even if the carb cleaning doesn't solve the problem, I obviously didn't clean it well enough the first time.
As a side note I tried the carburetor off of my parts car with the same results, except the engine died quicker. Investigation revealed whole mouse droppings in the float bowl and a completely clogged needle valve screen - both of which, I am assuming, are not good things.
Thanks again for the help.�

Re: Setting the Idle Speed
Like Bill said, go through every bit of it with cleaner and compressed air and a small wire,I also like to spray carb cleaner in every opening and see that it sprays out somewhere. Also make sure the intake manifold isn't cracked anywhere and the o-ring is good and sealing.

Re: Setting the Idle Speed
This may have been covered already in the posts, but not being able to get a proper idle speed may be a vacuum leak. I would disconnect the brake booster line and plug it and check for a crack or hole in the intake manifold. Some people spray a little carb cleaner around suspicious leak areas while the engine is running and listen for a change in speed.
Also, in the carb there is an idle circuit and if it is clogged, you have to open the throttle plates far enough to start pulling fuel from the low speed circuit, resulting in a high idle speed. I know it was suggested to clean the carb already, but the passages for the idle circuit are pretty small.

Re: Setting the Idle Speed
Good thoughts on the vacuum leak. I'll plug the line as suggested and see if that makes a difference.
A few things I noticed when cleaning the carburetor today: the needle valve sticks closed sometimes, and I don't have a rubber piston spring diaphragm (under the top cap.) Is this diaphragm necessary? Neither of my two coupes have them.
