Thanks for the replies.

I checked things again with a second voltmeter just to be sure. This showed 2.8 volts at the coil when the ignition is switched on and 1.6 volts when the engine actually starts.

I've found now though that the engine starts instantly first time even when stone cold.

Mike - voltage at the battery when running at a fast idle is 7.2-7.4 volts so this seems right eh?

Ajays in Katikati have NOS 6 volt resistors on the shelf so I am getting one of those just to try and see how this affects things.

Cheers
