I got the rebuild ztherapy carbs from Chris ( Grannyknot ) today, and mounted them this evening. ( pics to follow tomorrow ). But she doesn't want to start, if I use starterfluid into the air filter there's a reaction from the engine. So I believe it's not getting enough fuel. I did crank for quite a while with the choke on, but only little reaction from the engine. Any advice ? I'll look tomorrow again.

interesting point about the doors, I do know door height also changed over time here. I do know people where alot smaller in the 17th and 18th century.

OK compared to American cars yes, but they didn't have them here in Europe much.

Yes, heating up the old and using some wd40 or penetrating oil will most likely get it out. Forget cold. That's what I usually do to. But I would never use a helicoil. For my work I regularly need to drill out broken of 8.8 strenght bolts into cylinders all the time. What I do is grind it down to the surface, then use a pointer with hammer to center, then use a HSS drill, start small and go to the right size, then use a tap to make new thread.

I notice when driving in the Z that all the modern cars are much bigger and taller... I was thinking what this has got to do with ? Did the people grow larger and the cars grow with them, or they just made cars smaller back then? I mean when I stand next to a modern small car, it looks big from the seat of my Z..

New Nissan Z Car, Code-Named Z35, in Pipeline - Motor Trend It's a nice car, but they just don't make em like they used to anymore. It will weigh around 1300 kg, that's 300 more the the 240Z. And they are going 4 cylinder turbo I don't like today's styling features either, are the designers on drugs ? Those big wheels also look ridiculous. For me personally the old cars have a certain feel and emotion to them.. it's all metal and mechanical, while the new stuff is alot of plastics, computers and much easier to drive hence all the modern stuff, also more silent on the inside.

yeah and another z

I have to agree with you on that. Interesting to see prices in Japan and EU are much higher than in the US. Maybe because they are more rare, of has to do with economic prices?

I know there are still enough 240z's in the USA, but I would leave a 240Z alone, mod the 260 and 280z's...

Did they used metallics back in the day ?

240z emblem on the rear was series 1 right ? Datsun : Z-Series 2 doors Coupe in Datsun | eBay Motors

Yup, they are practically new, he had them on for a few hundred miles, let's hope the problem is solved with it... then we also know the answer to the problem.

Let's wait and see, I do agree with Kenobi, he has a point there. I bought the ztherapy rebuilded carbs from Grannyknot, and will put them on when they arrive, and see what happens...

I really want to order a set of rebuild 4 screws from Ztherapy, but they don't seem to respond to people outside the US

can you tell me what you adjusted ? I did the bellcrank mod, but maybe I shouldn't have done that.

I bounced up a topic in the carb section, that guy has exactly the same problem i'm having, curious if or how he fixed it..

I'm experiencing exact the same problem right now, so I'm bouncing this topic up, did you find any solution ?

nice !

I asked a professional carb rebuilding company from Belgium ( not so many around here ), and he says he doesn't understand why the gas pedal operates smooth when engine is off ( only on the pedal, because direct @ carbs you can feel the tensions of the springs ), but heavy when engine is running.

Cool. I like how they name the 240Z now in the segment of classic cars, because it's not such a known car here...

ýeah that's the million dollar question

Nice find ! I would put some new undercoating on the car, now you cleaned it.

Datsun : Z-Series 240Z RESTORED FLORIDA - 5K MILES in Datsun | eBay Motors looking good imo

Found this worth saving.. the 240Z is named as a classic and worthy investment..

That's really to low imo , I've set it just under 1000 rpm, like most cars do here. But I tried with the linkage unhooked, and feel how the butterfly valves operate on a running engine when turned by hand, and they still operate heavy, so.. problems with worn shafts then ? I can't seem to think of anything else at the moment. There's no play in the linkage. Could a to heavy damper oil, or a shortage of incoming air cause this to ? Altough I can't see a direct connection
