Hi

I am coming to the end of a large jigsaw puzzle that was an nsr250 in boxes and have now got something that resembles the original bike,but unfortunately I cAnt get it to start!

I have fuel, I have compression and I have a spark,but it doesnt want to go at all.

Is it possible to get the ignition timing that far out or something similar? Is there anything in terms of spark timing I may have missed or got wrong?

Any help would be greatly appreciated - I would reallly like to see this bike run again..
