Thanks Gav,
I did a little googling for photos of carbs, and it appears we have the flat top versions which I believe would have been standard on a later 260z that this is. I might need to take them off and give them a bit of a cleanup as it appears some birds and insects had found there way in there.
I am going to work on getting ignition working first. Then I will move onto fuel.
I believe the car drove to where I picked it up from and had not too higher kms... so we will see what years of sitting around have done to it. I was surprised it moved so smoothly when I cranked it by hand with a 1/2 drive ratchet. It has oil in it, and it seems pretty thick and sticky, so that might be a good thing. It cranks a little unevenly under the starter motor, so I presume some valves that were open may have gotten some corosion on the seats and reduced the compression. That may fix itself a bit over time. I really just need an engine that runs well enough to get rego. I'll spend a few to see if this can get running, but if it turns into a big job I will give up.
