GL1100 Carb rebuild?

I'm with Ken on parts. Rarely will I buy stuff before I do a inspection. How would I know what I need until I look at it. True, some things can be counted on to get replaced, like O-rings. I keep various kits of those things.

Certain O-rings work better than others for certain things.

Black - they WILL swell. Sometimes this is a good thing. I use the black O-rings for the intake elbows. The size that I use is a tight fit to the groove in the elbow. Tight enough to hold itself in position within the groove until I install them. Once installed and hit with fuel, they swell to make a perfect fit. I've never had one fail.

Green - these are generally sold for air conditioning repairs at most better auto parts stores. They can be used in fuel environments and do not swell like the black O-rings. Actually, I use the green O-rings as a replacement to the rubber plunger supplied with the syringes I use in my Stealth Tester fuel testing kits.

Brown - Better (generally considered) than the black or green for fuel use. Most have various amounts of Viton in the mix. More expensive and harder to find locally. In Industry, brown O-rings are generally considered the best O-ring available by those that work on vehicles. That really depends on a lot of factors though.

Lighter Colors (White, Yellow, Orange, Red, Blue) these O-rings are generally silicone-based and have limited use for us in a fuel environment. Many of the lighter colors may also have Teflon in their mix and are great for Brake master cylinders.

There are many technical aspects to O-rings but some use this jargon to their benefit. "Technically" we're working with fuel within either a vacuum or a overpressure and it's not that complicated.

____________

A color guide is a loose reference to usage for O-rings. Manufacturers have not gotten together and set color reference standards because of the various "secret ingredients" that apparently make one O-ring different from its identical counterpart. We see this in the marketing of 0-rings.

Common sense plays a larger role than the technical spaghetti-reasoning for the almighty dollar.
Some will say, "You get what you pay for, and a $0.35 o-ring will fail!"
I say, "Ok..." and move-on with my cheap O-rings. haha

For a variety of reasons, I don't sell individual orings.

I tried that as an experiment a while back. The results were quite poor from my point of view.

Not only did it add labor to our business model, but it also defeated significant quality assurance steps built into our products and introduced new potential errors. It also encouraged "shortcuts" by customers who re-used spent used parts and incorporated inferior new parts from other suppliers.

That led to an increased customer service workload for our staff.

Our philosophy: there is too much labor involved in a proper carb to encourage anything other than "best practices."

But, individual orings (in the most common sizes needed for vintage Hondas) can be purchased from this source:
