No spark - IRK gaps etc

[jmadden91]

Hey guys, so I ran a tank of 2 stroke through the bike the other day.. and it stopped haha. Replaced fuel with normal unleaded cleaned out the carby and chucked a new spark plug in it and it started up again. It stopped again after a few seconds and after a quick check im getting no spark from my irk.. not sure if its a coincidence or whatever but its stopped. What kind of gaps should I have at points 1,2 and 3?

Cheers
