    Default Linkert MR-4 A

    I got this carb. from Doc's H-D in St. Louis about 20 years ago. I've seen MR-4's, but none like this with the inner body being the venturi. It looks like the air cleaner side of it was machined and the air cleaner mount was made and welded ( soldered ?) to it to give that end a larger bore. Doc raced 45's in the '40's and his son Ralph race K Models and CH's in the 1950's and '60's. Any info would be great.
    Thanks Craig

    Craig, many of those MR4-As had full length custom venturis. I have one as well. Here is a copy of a factory blueprint for them..

    Thanks to both of you!

    But Craig's smells wildcat to me.. and it ain't even in my hand.

    The one Factory mod that was anyway similar, that I did hold in my hand, was Michael Breeding's offering of a Reiman carb at D-port years ago, and I barely knew what I was looking at. (Although I met the Reimans of course; They were local,.. but I'm ignorant.)

    It was a machined body for a large venturi sleeve, not a sweat-soldered assembly like Craig's.

    Such a bowl extention is also displayed at http://www.beautyofspeed.com/gallery...rt/linkert.htm

    You can never have too much reserve!

    PS: It came with two bowls, Craig?

    Fabulous.

    Cotten; Yes. It was in a bin box upstairs in the shop. There may have been DC carbs and Tillotsons with it. Possibly race carbs, but I know nothing about them. Except that I have a few boxes of them.
