Superb! it's vastly improved cold start. Took around 3seconds to start and only had a slight miss fire for no more than 3seconds. Altered all the crank rotation sites as stated and got her up to 50*C where it would normally back fire on crank and it started faultlessly. Minor adjustments to ignition advance for a stronger idle and it just sits there humming a nice cammed note Excellent Si, thanks for your time!
