I finally fitted my modified cam to one of my mowers today. I left the factory kill wires in place and didn�t modify the cap for adjusting the idle. It just so happens it idles nice and low with the throttle down as low as possible before moving it to the stop position. There is then a decent throttle response up to the run position. I didn�t let it fully warm up to see how it runs when at operating temperature but I was happy with it. I may also change the large poppet retainer over to a small type at some point, I�m not sure if this will affect the speed of throttle response or only the governor response. Overall my one worked well from idle to run, kill wires worked as normal and was a first pull starter with the cam mod and metal needle. I�ve gotta thank Norm for his work on this one and input to the forum in general.
