Right I've managed to get my current pump to pump properly. I used an air compressor and blew through the pipe to the fuel tank and the fuel gushed out like a beauty. so problem solved there.
But now, low and behold I have another problem, I bought an electronic ignition kit to go in my current Bosch dizzy. Took my points and condenser off then tried to fit the new electronic ignition in place but it wouldn't fit. So I think they have sent me the wrong one. So I reinstalled the points and set them to 0.45mm and now the thing hardly starts and when it does it back fires and pops and bangs. I have checked the cam timing which looks ok fiddled with the dizzy all day today and can't get the thing to run right.
I am at a loss to what it is. The one thing I did notice when I first took the points out was that there was a washer wedged between the dizzy cam and the side, I just took this out and thought surely that shouldn't be in there. But that's all that's changed to be honest.
Points seem to be sparking good too, right firing order 1342 clockwise.
The only thing I can think of is that maybe the washer was a bodge for something.
