Hi Grumpy, did take the emulsifier out and blew and sprayed out and when held up to the light was able to see through all holes, the idle jet was done in same way ( except you cant see through it ). Instead of using a piece of wire probe I borrowed an assortment of sewing/darning needles off partner. The mower will idle smoothly and when you increase the revs it picks up just as smooth, runs well until it hits a thicker patch of grass, it still does as I mentioned in my first message.
