how many ks ?

Have you changed the fuel pump in it ?

Have you sprayed aerostart to see if it fires ?

If it has fuel & spark & air, then it's timing.
Well that would be my train of thought if it had carbies & a distributor.

Sorry, that's not much help, but I live in the technology dark ages when it comes to engines. If it stops, then I can work out the problem fairly quickly.
These modern things are a mystery to me!

How did you confirm it had fuel and spark ?

did some more tests today and it doesnt seem to be getting strong spark.

its getting spark every now and then, the coil, plugs, leads and distributor cap look new.

leaning towards electronic ignition module in the distributor?

what do u think?
