Hi Joel, thanks for that, but the floats are not the cause, as I said I have a box of them plus new ones I have never used but I will give the ones you sent a try. I fit a new primer cap and needle to every one I do, but the frustration comes when these new components fail, and in some cases several times before I get them settled down. When I have a failure, (flooding cap) I immediately fit another needle and often this fixes the problem. The failed needle goes in a container with failed needles.If the second needle fails I fit another needle and another cap. This usually fixes it but at this stage I don't know if the problem was with the needles or the cap so I end up with a mixed bag of needles and primer caps, one part is faulty but at this stage I can't tell if it was the cap or the needle. I then have to go back through and test these bits with other known working parts to try and eliminate what the faulty bit is. It is all very frustrating and time consuming as well as the running back and forth sorting out the problems with the customers mower all over stinking little float needles and primer caps that all other manufacturers seem to be able to manufacture easily. I appreciate the fact you have been able to get these made which is 100 times better than the plastic rubbish but a simple thing like a float needle shouldn't be this hard, CTS have been making this sort of stuff for a long time
