After years of head scratching and pulling Ford B Zeniths apart until I am blue in the face I have finally cracked it !

After all the usual cleaning and poking with bits of wire, cleaning the jets with number drills, setting the float level to the correct height and what-have-you, I have now got a carburettor that runs as it should. No skipping, doesn't stall at junctions and accelerates as it should and here's how.

My pal is a skilled clock maker and relies heavily on his ultrasonic cleaner for the removal of years of muck, grit and grime. For the sheer hell of it I pulled a Zenith apart this morning and submerged it in his ultrasonic parts cleaning for 30 minutes. I couldn't believe the amount of muck and grit that ended up in the cleaning tank. I repeated this procedure again for good measure, following which I rinsed the Zenith in cold water, blew it out with an air line, then immersed it in thinners for a final rinse and then another blast with the air line.

Reassembled the Zenith, filled the float chamber with petrol, fitted it to the
car, crossed my fingers and made a wish.....lo and behold, not only did the car start immediately it ran without stumbling and idled with the GAV fully closed.

Equipment needed is: One 6.5 litre cleaning tank and 5 litres cleaning fluid.
I think the cleaning fluid is water with a couple of shots of "truck cleaner"
added to speed up the process.

Give it a go ! I worked for me !
