Yes like I said you should stop messing with it, remove the plug and leave all that excess fuel to evaporate over at least 3 days in my opinion
Thanks Jim this to me is key to the problem here, bloody technology causing trouble, what use is an auto choke for riding it around a block of garages...no wonder it's flooded.
Whats the betting our kyle is always starting it up just to see it run, hear it, smell it...just lie we'd have done all those years ago. Trouble is now it's dumping fuel in and never getting hot enough to switch off, least we could just push the lever / knob back in just as soon as possible.
