A car could be running before but things may not have been aligned and was just enough to run. Since the head is off, good to check if everything is buttoned up.

When he was born, his mother did not want to give him a name, tried to give him up to the state, tried to trade him for a pitcher of beer, he was sexually molested as a young boy, he could barely read or write, robbed a store at 13 years old, never really knew his father.  So I could just imagine, the lack of love in an environment he was raised in. I am condoning what he did, it was horrific but from the get go, when he was born, he was set up to fail and became a delusional sociopath.  His background and lack of love did not contribute to him hating society?

In away that article is true, the GOP has squandered their opportunity. We will have to see, I just don't like the tax bill they are trying to pass.

Before you do this, did u check for vacuum leaks..previously I mentioned to check your carb adapter for flatness. You can adjust your carb as many times as u want but if u have a vacuum leak, it would not matter.

What I do and seems to work is when I adjust my mixture screw, not more than 1.5 turns out, I take the car for a test drive, not just the streets but freeway also and pull over and check my plugs. You don't need AF gauges! Back in the days, the would b mechanic would smell the exhaust, check spark plugs and pay attention to how many turns w screw driver. Plugs should be like tan color, not too white, lean, and not sooty black, rich...u want in between. Been doing adjusting on old carb cars, American and Japanese. If u r not sure how to go on line or you tube how to adjust 32.36 weber, very easy to do.

If you backed off mixture screw, you are richening the fuel mixture. Are you sure u know how to adjust your carb?

I know this from experience if its not flat, it can cause a vacuum leak. What's worse is the 2 adapter plates. And u can't overtigthen them, it can get warped. One way to tell is spray some carb cleaner around the carb base, if rpm goes up, there's a leak and if you tighten it and still leaks, then strong possibility its warped. I would also spray carb cleaner around intake area. I'm just saying a lot of problems we faced w these Datsuns is simple. Good to do a diagnosis first before replacing parts.

Yep...best to to through the whole vehicle, cooling, exhaust, engine, ignition, lights, brakes but do one section at a time..

Wayno, actually my 510 has been a DD for 15 years or so. I do agree you have to dial it in. I guess what I'm getting at is that these cars r 40 years old and more than likely one will need to work hard at it to make it a DD.
