I spent a fair time today trying to get them going properly, to no avail, it still starts badly, runs badly, all accompanied with black smoke. Given that it is unregulated at the moment, I think it is a fair guess that it could be the problem. I also have the heatshield off my old carbs that looks like it will pretty well bolt on, so I guess its going to get a polish up. As for the fuel pump switch, I have another project on the go with regards to that..
