Thats interesting CB. I will be removing the ones on mine. Meantime, still feeling it was fuel shortage on mine I raised the needles to the max then found a 140 jet on ebay. Felt in my water that the thread would be different. It was. 0.8mm pitch as opposed to the original 1mm. Did find a die on line but the price ! Gave it some more thought and remembered a couple of thread files I had years ago. Found them and with a 1mm section- result. Just tickled the thread enough allow a fit. Did this with carb in situ. While on my back checked the float height with the gauge I made earlier. AOK. Now the interesting bit. For no reason at all I lifted the floats up to the max height ---- they stayed there WHAT !!! Repeated - same thing. Cause - they were being held up by the f/bowl gasket supplied in the overhaul kit.
Eased to clear it. Will let you know the result.
How did Pratt & Witney ever get their twenty seven cylinder radials to run right !
