Hi Gadge, the thing is with the carby mods I do to the cam, all that does is to allow the cam to rotate smoothly(getting rid of the lumps and bumps on it) this then takes away the strain that is put on the cable trying to force the lifter up and down over these bumps. The second part of the mod is to lift the cam so it shuts the poppet completely. This will stop the motor when the throttle is closed. The next part of the mod is to fit the screw in the cap so that you can screw it in to open the poppet to a point the motor will idle, that is all this does, it does not improve the starting.What it does is give it throttle control. The thing that controls the starting is the float needle, if it leaks and floods, no hope, if it doesn't allow fuel to flow no hope. I have also found that with this needle mod I can leave the fuel on and it doesn't leak or flood. This is often a problem with the Victa taps in that the don't shut off 100% or if you turn the tap a bit far when you turn it off they can pass and you end up with a flooded motor
