G'day AusAnzani thanks for the help. The carby is held on with a hose clamp so looks like plenty of room for improvement. I had started to think it might be a bit daunting but you've given me back some confidence. Thanks again mate.
G'day Kye thanks for the tip off. I don't have Facebook so my Mrs just signed up to your page and she is quite impressed.
Im in the area called the "Golden Plains" which is halfway between Geelong and Ballarat. Around 2 hours from Hamilton, where those motors are Kye.
