Scott E Posted June 28, 2020 Report Share Posted June 28, 2020 I put Walbro needles in my K65 carbs but still had a float problem with one of them. I got out a magnifying glass and looked carefully at the hole where the needle seats to shut off fuel flow. It was just a flat surface around the hole, which had a sharp, 90 degree edge at the hole. That sort of works with the original needle that just has a flat washer on it's tip. The Walbro needles have a 35 degree V shape that should sit on another 35 degree surface to seal properly. I machined a 35 degree point on my lathe on an old 1/4-20 bolt and then turned it down so it would just fit in the pocket where the needle sits ( .175 inch OD ). I then put it in the needle pocket point end down and taped it with a hammer. That left a nice 35 degree V surface where the needle sits. My leaky needle problem was immediately cured. I went ahead and did the same thing to the other carburetor. I was having problems with both my carburetors running rich and lean randomly and was never able to get them properly adjusted until I "stamped" that 35 degree corner where the needles sit in the carburetors. After getting that done the engine drops to the exact same rpm at idle every time and I was able to set the idle mixture needle jet on both carburetors at idle without it changing randomly even as I was attempting to adjust them. I was also able to set the long needles for a proper mixture ratio at speed. Before I could feel the engine running too rich and then too lean randomly at speed. No matter where I set them the plugs were always black from running too rich but the engine would also run too lean as well at times because I had the needles in the upper clip slots trying to fix the running too rich problem. It's like I put two new carburetors that actually work properly on my Dnepr MT-11. Quote Link to comment Share on other sites More sharing options...
