1966 FLH Linkert DC7 Info Please

Do you think your carb support will still line up, Gitguy?

Not much profit in just a single paper gasket!

Think you want to gamble on the insulator material's fuel resistance, when it ain't in the Book?

DCs are awesome. Can you guess what the first S&S carbs were patterned after?

This is what I found on the ITW site regarding the gasket situation, Cotten. That's where the confusion is from. I saw the parts manual showed a single gasket and then I came across this.

Thanks for sharing your experience with this Silver. Maybe I'll snag another swing arm pivot as a spare. Then there's Jerry idea of an extra float bowl at the ready.

So now I ask myself "Why do I want to remove a perfectly good carb and replace it with this?"

I have been running my 65 sportster with a linkert DC for about two years and what swelled up with the ethanol fuel was the float swing arm pivot ( the white nylon piece that lifts the needle valve) to fix mine I enlarged/reamed the pivot with a little larger drill bit than the pivot shaft/rod and shaved the ends with a razor blade and started using non ethanol (recreation)fuel with a oz. of mystery oil every time I fill up. The float has and was not affected at all and have not had a problem in a while.Took two times to get it right and I keep a spare Float lever block but have not needed. IMG_1618.jpg

That basically the same carburetor used on Sportsters from 1957-65. I have had the floats hang up on me a few times due to ethanol gas getting everything gummed up. On long rides I carry a spare loaded float bowl that I can swap on if need be.

The Parts Book just shows a gasket, Gitguy!

The cast iron manifold and cast iron throttle housing won't distort nearly as bad as aluminum, bronze, or potmetal.

(The notion that multiple gaskets seal better is fallacy, as they allow distortion.)

I'd still grind them for inspection anyway, of course.

My obliged, Mr. Cotten!

Now I have to solve the gasket mystery . . .

Cheers!

Graciously, Gitguy,...

There is ample room in the bowl for the float to swell!

I produced a batch many years ago, but received zero feedback.

When I bought this bike 20 years ago it had a Super E installed but the original Linkert DC7 came with along with it. I've always wanted to get it back to it's original state. I bought a rebuild kit for the Linkert years ago and finally got around to the rebuild. It was apparent that this carb had never been apart since it left the factory back in the mid 60s. All the parts were there but it needed a good cleaning. Being a pretty simple device it went together rather easily with new seals and gaskets and the float set according the the manual: 1" +/- 1/64" from the edge of the float bowl.

So I have a couple of questions. I am concerned about this 55 year old float and how it will hold up with P4 ethanol. Anyone have any experience with this (Tom Cotten)?

Also I am uncertain about how many gaskets/spacers are required between the intake manifold and carb body.

Thanks for any input!
