Hey guys, thanks for the help.

Sussed it out, the ignighter had packed it in..... got a new one from a RT142 Advante, works a treat. However it was still doing it a little, turned out id got some chep shit fuel somewhere in the last few weeks..... the fuel fillter was cloged up with what can best be discribed as rusty water. In the end it was a combination of fuel pressure and lack of spark.

Cheers guys
