Incredibly Clean & Original 1973 240Z on BaT

I don't know the secret code to get a comment out of moderation there, either. On the other hand, I only tried once and figured that the moderators don't try or don't care about allowing posts outside of a select group.

You know I had to chime in here.  Still amazes me that people are promoting the technically inferior SUs over the Flat tops, which are stock for this vehicle.   I think most do not realize the advances that were incorporated into the flat tops that are not on the SUs.  The flat tops feature 1) factory aligned needle and seats 2) a visible glass float bowl level 3) Anti-stall fuel rich mechanism 4)  multi-point adjustable fuel mixture screws 5) fuel pump accelerator.  I would bet that most who are promoting the SU’s are unfamiliar with these features and have no clue what I am talking about.  Personally, this car is about as good as it gets…I even love those hubcaps!  OK, no more carb comments from me…I will go back into hiding.

I tried to post this comment on the auction site, but looks like they will not allow it....perhaps it is too inflammatory.  

Maybe I should try to sanitize it and then re-submit.

I assume that both of you guys both are registered members on BaT?  I know that I have seen motorman7's comments before. Some comments will be flagged by members as "not constructive" and then the moderators at BaT will review and decide if the comment is indeed "not constructive". However, the comments usually have to be pretty harsh or inappropriate to be removed.

They took my sanitized version....glad they did.

Interesting...My original comment took about 2 hours before it was posted.  The sanitized one posted immediately.  Guess i need to be nicer...now I have a double post....oh well.

I had a bad experience with flat tops as a teenager.  I couldn't get them to run right so I took the car in for repair (about 1978-79).  I had the carbs overhauled and the guy still couldn't get the car working right after 3 returns.  It could easily be my ignorance but I would be scared to death to have them so I remain open minded about the flat tops.  But... those hubcaps have got to go.  :)

I registered and commented. The comment was trapped in moderation and never saw the light of day. It was not critical, the slightest bit obscene, or anything that would go against community standards. I thought it was odd that it never left moderation, but I didn't try to pursue why they left it in purgatory.

It was our discussions in Atlanta, wasn't it?     :beer:

Don't forget about the built in return springs.
Or the heavy calibrated weighted suction pistons.
Or the heating water that goes all the way around the nozzle to aid in fuel atomization.
Or the real choke function.
Or that they came with an automatic thermostatically controlled air cleaner.

OK. Back to the boat with thee.

That's why I'm about to turn my SUs into throttle bodies. LOL

In 1973, didn't the 240Zs with the flat tops come with asbestos wraps on the fuel rail?  They are missing on the subject '73 on BaT.

in 73, I'm not sure if that heat wrap came from the factory or was added by dealers as part of a TSB.  If you look at the pics in the FSM's, the heat wrap does not appear in the 73 manual, but it is shown in the pics for 74.

@Zup might have some insights. I think he and that wrap stuff have a long and troubled relationship.   LOL

Was the heat wrap really asbestos?

I thought I read somewhere where the '73 also came with an electric fuel pump.   Is that correct?

The electric fuel pump was a field modification designed by Nissan and installed by dealers. I don't know if Nissan ever shipped any 73s with the fuel pump already installed.

As time went on in 73, I believe the asbestos (Zup has mentioned it was indeed asbestos) heat wrap transitioned from the dealer installation to factory.

Zup replaced the heat wrap with a more modern equivalent because it had deteriorated and became crumbly over 40 plus years with no way to restore it.

Yes. Both the insulative material inside and the outer covering were described in the Datsun/Nissan TSB as being made of asbestos containing materials. 

Evil stuff for your body---but in '73 the governmental authorities weren't worried too much about it---they were more worried about the perceived threats of psychedelic drugs----:ENVOUTER: (Ken Kesey and the Merry Pranksters, The Electric Kool-Aid Acid Test had really set in)

Many 73 Z'z came from the factory with a "transistorized" electric fuel pump---either the Mitsuba FP3 or the Jidosha Kiki units (mine had the Mitsuba).

I'm pretty sure the cars from the first few months of production (72 builds) did not, and were candidates for the V3 factory authorized TSB program to address the reported issues----the electric fuel pump and heat wrap on the fuel lines were 2 significant aspects----but there were several other procedures included in that TSB.

The transistorized electric fuel pump was not listed on the window sticker as a feature of the car.

I'm not wound-up tight enough yet to get into my rap about "the wrap" today.

I do think It will be interesting to hear Fred Buoni's response regarding the TSB/V3 issue as it relates to ZCCA/ZCON judging for this unique instance applying only to the 73 240z. He promised a statement in an earlier inquiry by @motorman7regarding the interpretation of the TSB/V3 as being "Factory" or "Dealer".

Looks like the subject car is an early '73, built in 11/72. That would explain why there are no heat wraps on the fuel rail.

Just finished an article in the July issue of "Automobile" in which a number of big names discuss the current state of the collector car market.  They generally see the market softening for high-end stuff and it may be considered a buyer's market.  Japanese imports were mentioned several times but not the HLS30 specifically.  Their opinion is that the Japanese market was strong with reservations for some of the exorbitant sales like the Toyota Supra Turbos.  Recommended BUY for the average price 1972 240Z of $25,000
