Hi guys, I overhauled the carby today. Got a kit from appco. After spending a few hours cleaning and assembling I got the engine running again and its running absolutely perfect. Very happy with it now. Only things that stood out in the carb as being a bit dodgy were a perished accelerator pump piston and a really clogged up brass filter at the inlet before the float valve. There may have been crap somewhere else in the carby or a leak but nothing I saw. Anyway its running great now right from cold. I couldn't be happier as I was worried that it was just how datsun engine ran and Id have to warm up before going anywhere.

cheers,
Cameron
