Linkert Carburetor For Classic Harley Motorcycles

 

I had originally posted this Linkert carburetor info on the forum here at CAImag but I wanted to put it on my blog page. More as a test than anything else as I hope to start doing some video to make the homepage here at Classic American Iron magazine more interactive. I may even get energetic and learn how to put together a classic Harley PowerPoint presentation just for grins if I can think of something interesting to present. If anyone has any suggestions, please pass them along.

Anyway, the video is a view of the throttle bore of a Linkert M51 and the action of the fuel nozzle. As the throttle plate sweeps past the idle transition hole, the main nozzle comes into play. This is called the “tip in” as fuel is mixed with air from the bleed holes in the nozzle a “bubbly emulsion” is drawn from the tip, enters the manifold and the cylinders and, on the compression stroke hopefully goes bang!

Above is a nice diagram of the fuel nozzle function. As you can see, as more demand is required from the engine, the fuel level around the nozzle drops and the air bleeds are progressively uncovered. I also just noticed that the diagram shows a “gasket” between the nozzle and the venturi. I’m curious if anyone knows that use of a gasket there was common procedure.

For my next trick, I plan on videoing a rebuild and assembly of a Linkert carburetor and we’ll go into more detail. Stay tuned.

Thanks Classic American Iron Magazine! – Mr Big

1941 Harley Davidson WLA and 1951 Goulding Ls Sidecar

A little over a year ago I was happily cruising around on my 2003 Harley Electra-Glide and had become a member and reader of the American Iron Magazine Forum. I kept noticing a link to a “Classic” forum and thinking that I was a classic kind of guy decided to investigate. Having spent some time building classic cars this seemed like it would be right up my alley. Little did I know what I was getting myself into.

I was immediately drawn to the vintage Harleys being discussed and couldn’t wait to own one. It wasn’t long after that I found and purchased a 1941 Harley Davidson WLA. When it arrived, I was just mesmerized by it. I had to know everything about it. And to give you an example of how little I did know, when my buddy and I first rolled it into the garage to look it over, we both saw the fuel shutoff on top of the tank and neither of us had any idea what it was. I had a very long way to go.

Fast forward to today. With the help and tutelage of my many new friends on the Classic American Iron forum, I started this blog, made over 1200 posts on the forum, traveled to Wauseon, Ohio for an AMCA meet at the invitation of a forum member, assisted in developing a website dedicated to the Goulding sidecar (www.gouldingsidecars.com) with the grandson of James Goulding, found and purchased a 1951 Goulding sidecar, rebuilt several Linkert carburetors, and the most important, had a blast doing it.

So, without further ado, I would like to extend my heartfelt thanks to Buzz Kanter and the American Iron crew for making the Classic American Iron magazine and forum available. As a total newbie to vintage Harley’s, it would have taken me years to access the knowledge I have gained without the support of the forum and its members. Thanks again to all of you and a Merry Christmas to you and yours.

Mr. Big’s Blog – “GouldingSidecars.Com”

Welcome to www.GouldingSidecars.com.  Still kind of amazed at how all this came about but here’s the story.  After purchasing my 1941 WLA Harley Davidson last year, I was cruising the forum here and a vintage bike with a sidecar caught my eye.  Not sure why, but I was just drawn to it and I could picture myself being a “sidecar guy”.  I made some inquiries about what would be correct for my bike and forum member “Sarge” gave me a quick lesson on Goulding’s and the Litecar or Ls sidecar that was manufactured for the HD “45”.  He also pointed me in the direction of “Clydeflathead” (Dave), a forum member he knew to be well versed in this area.

I contacted Dave and from PM’s to emails to phone conversations a couple times a week, the search was on.  Just one of the nicest guys you’d ever want to meet and he was more than happy to educate me and assist in my search for a Goulding sidecar.  He told me about the friendship he had developed with Ron Rae, grandson of James Goulding and author of The Goulding Album and how they would meet periodically to discuss all things Goulding.

The more time I spent chatting with Dave, the more impressed I became with his passion and thirst for knowledge on the Goulding sidecar.  I told him that all his research was fantastic and he should write a book detailing the technical aspects of these sidecars.  Ron had covered the family history in The Goulding Album but there was nothing out there for the enthusiast wanting information on Goulding sidecars for their restoration.
