Making good progress now with the rebuild,and have taken some photos for the record. did have problem with a rusty inside of the tank but have put gravel in and given a lot of shakes,also washed out many times and I think its okay for the moment. One of the pictures shows the fuel bowl and fuel lines. I have made the one from the tank slightly special. I have made the pipe similar to a sink P trap and any rust will because its heavier than petrol will settle in the trap.also with the fuel line clear I can see when it needs draining. WIZZARD EHH !
