Hi Norm, I have a couple of questions for you about your carby mod, if you could offer some answers that would be terrific. I have been thinking about doing this to a spare carb for some time, as I have a couple of machines I use regularly that I think are in overall pretty good shape (seals, viton tipped needle and seat, clear jet, good spark, good compression etc.) which I can never get to start first pull cold. They often start second pull, run perfectly and restart easily hot. I donοΏ½t run them out of fuel to stop them but use stabil in the mix. What is the starting procedure with the modded carby? Throttle to run, single prime then start etc? Or are they all different and once you find a procedure that works for that machine go with it? Can I do the cam mod and not do the idle control screw or kill wires portion of the mod? I know I could try this all myself but wondered if you had some ideas already. Cheers, John
