I’ve sent another reply but i believe the anti-spam/system has caught my message because I also added some pictures and video links for how it runs for any noises and the fuel pump.
Just in case that was a problem both cylinders are hot, they’re both obviously firing but the front cylinder is obviously leaner than the rear, it’s squeaky clean white. the rear has just a touch of tan. Obviously the carbs haven’t been off yet but it’s interesting to see how lean it’s actually still running with.
the threads on the plug don’t look very hot at all, there’s a band of black around the first 2 threads, gradually tapering down to normal metal colour over the next 3 or 4 threads.
thanks again Marcel
