The original shape was a circular cylinder shape with ends shaped to fit into the beveled carburetor body on one side and a similar shape to the clamping ring. The leaded string was then forced tight when the plate was tightened.</div><div><br></div><div>'O' rings are supplied now but are not always a tight fit.

<p class="MsoNormal">There are very few things that I find when restoring Austin-Healeys that surprise me anymore but today, while dismantling a set of carbs for a BN2, I came across this at one end of the balance pipe. The correct part is a rubber gland seal
but at some point it was replaced by some black plumber packing string, just shook my head.</p>
