thanks for the diagram - it is the same one from my service manual - good info.

the air filter is in correctly - checked.
needle in point end first - checked.

very unusual.
it did stop working only after i touched it and replaced fuel filter, plug-cj8, air filter, cleaned carby

it does give a spark against chassis.
fuel seems to be getting to the spark plug.
weird


anything else it may be ?

thanks

greg
