Hello good news, after a good 48 hr soaking in cell.thinners I blew all the holes out with an airline.I then filled a syringe with thinners and squirted into each hole and they were all clear, even the very small one which I was worried about, a jet of thinners came out of it.Next job to reassemble and try the carbs.out.Why it looked as though it may be blocked with solder,it must have been the residue from the thinners.If it had have been solder it would never have worked .Then onto the problem of flooding and isolating which part is causing the problem.Thanks for all the help.
I was hoping to give my classic car a run after it hibernating for the winter, but since the weather is so awful and I don`t want any rain on it, I can concentrate on the Douglas.At least it isn`t snowing as they said it would Len
