Hi folks. I've searched the database and web but can't find the nominal resistance values for testing the magneto coil.

When I spin the motor by hand the spark looks weak and intermittent. I don't have the experience to know if that is normal or if it is the reason the engine won't fire after putting it back together.

The multimeter jumps to show there is some connection charge passing and as I say there is a weak spark at times.

I'm loathed to start buying spares until I know something is dead.

I'm pretty sure the fuel is getting through as the exhaust smells of petrol after trying to start it. Do you need to prime the carburettor or is it self priming when you turn the engine over?

Thanks for the help.
