Yesterday I noticed that there was some discoloration on the float guides on the right side float chamber, the left side was clean. ( You can see it on my previous blog, photo one ) It appeared to be some type of waxy buildup, just above where the float sat in the empty float chamber. I polished the guides with steel wool, which removed the discolouration very easily. Now I just need to get the new floats, hopefully within the next week.
