This is just a thought, but it could be the problem, I know it sounds stupid, but the stupid things are the ones that get missed every time. Here goes. The SU bowel vents are plumed to the stock air box outside the air filter. Check the vent plumbing to be sure this is the case, if you are getting manifold vacuum to the bowls it will idle bad and do all kinds of funky things through the RPM band like backfire through the carbs, exhaust, stall and restart etc. I know it sounds like an elementary mistake, because it is, but try just pulling the hoses off the bowels and see what happens, cant hurt, rite?

Two words..............."Truck Stop"....................Pre '74 cars have a diesel style filler neck as does any vehicle not covered by the unleaded gas federal mandate. Matter of fact, my Bobcat fuel cap and hydraulic reservoir cap both fit my '73Z.

Thats a problem, if you are showing 3/4 full (at full) and 1/4 full at empty you are only using 1/2 the gauge range over 100% of the sender range. Disconnect your gauge at the sender and see what it reads, should show empty. Next jump the gauge leads out at the sender, gauge should read full. this will basically test your gauge for function but not calibration.

Are you sure the tank is empty when you are showing 1/4 tank? Its not likely that the calibration is that far out at the gauge. If you are sure the tank is empty, add like 7 gallons of gas and see if the gauge reads 3/4 tank. If it does, bend the rod to evevate the float till the gauge reads a half tank and you should be good.

First class would be a reliable source of cold Bud in the bottle, some good Tex-Mex and a bar tender that will be willing to tune into the Ravens-Browns game on the 4th. I aint hard to please. Still in the planing phase, we want to come out via I-40, and return across I-10 then up the blue ridge parkway, or I-95 if we have weather in the mountians. Should make for a nice 7 or 8 day road trip, with a cool place to law over in December. Gives me like 6 weeks to get things strait before going to the Head Shop convention in Vegas in Feb.

I've been talking with a long time friend, and if we can fit this into our work schedules, we may just pop in on this event. Being self employed, I know I can make it, but having driven cross country many times before, I don't think I want to go 1600+ miles (each way) without a capable co-pilot, considering my car is a 73, and hasn't been restored, just maintained.

Has your car been converted to a power steering rack?! Why would you put a damper on a manual steering rack for non off road use? If anything the car should steer easier. Put it on the shelf as a conversation piece.

I think you are reading a bit much into that. Vacuume drop perhaps?

Wa-WHAT? It's caled a "CROSOVER" because it "crosses over" the load. The transformer keeps the inductive load "stable" when highs and lows of music signal pass through the coils of the speakers. That little resistor you see on the back of the speaker is there to compensate for heat buildup in the coil of said speaker, in parallel, to provide for the reactive inbalance. If you take two 8 ohm inductive loads in parallel, they effectively form one inductive load of of under 4 ohms, depending on signal intensity and strength, not like a set of resistive loads which will devide themselves in half over the circut. If you place succesive inductive loads in series the resistance will degrade with each load as the magnitute of the power source deminishes through the previous load or device. This is the reason you can not wire unregulated alternators (AC generators) in parallel or series. The back feed voltages become circuit fatal to the individual devices over time. Of course all this depends on the intensity of the power generated, again we are talking 4 watts. We are however talking a 40 some odd year old radio that will be a PITA to replace. Buy the C/O and be happy.

I have a neighbor that has a racing lawnmower, I kid you not, it goes like 60 MPH. I built a gocart I see the crowd appeal, I see the novelty, I just don't see the challenge, for lack of a better term, in building a tire shreader. It's not that I'm getting too old, I'm as juvinial as the next 7th grader (at the ripe old age of 46) I don't want to come off as a butt head, but really, it seems ELEMENTRARY to put all that good power to waste. After all, he could be going fast through the twisties and pleasing himself, as apposed to doing doughnuts for the thrill of others. Yes or no?

It must be great to hit these parties in the zero rust states and have a bunch of S30's all in one place, the last time I went to a event like this in my neck of the woods the closest thing to my Z was a 300ZX. The HLS30 is a dynosaur in MD........................Extinct.....

Once again, the radio is designed to supply an INDUCTIVE LOAD. The crossover is an inductive load that modifies the output to support multiple inductive loads, they cost like $20.00 and are the size of a pack of cigarettes. Doing things rite the first time saves time and money, and in this case the original radio.

Impressive. OK, not really, we aren't talking about get ready to drag race and hook up the hot rubber, we are watching a guy simply burn tires off his car. Cool way to exit a wedding though. Let me ask you a question Ovenfood....................Would you take those two beauties to a burnout comp, rather than a race track?

When trouble troubles me, I trouble trouble........................Unknown. 49% of the people in the world are of below average intelligence. That’s mine, so if anyone wants to use it, it will cost a nickel, at least the first three times, unless I get the credit

If the bench adjustment was so far off that the valves weren't closing and allowing unspent fuel to explode into the exhaust system, yea, theres a problem. The cold adjustment of the valves should be loose (noisy) but the motor should run well enough to get through the break in period at which point you take it to him and he does the hot adjustment. It has no relation to a carb setup, the carbs are flow bench adjusted to a meanial standard, whereas the valves are adjusted to a known set of mechanical measurements. Worst case, the builder should have told Zdude to do the brake in regiment and then come in for a hot adjustment, after all, it's not a track car with a pit crew, it's a classic car with an old fangled in line 6 and a shade tree mechanic/ owner. (No offence Zdude)

Speakers are inductive loads, not resistive loads, the speakers will sound like crap in series, you need the crossover to run two 4 ohm speakers and get any kind of sound quality.

Go look at the car and decide if you want it, but don't get into money with the seller. Tell them you'll have to "think about it". Get your drop dead price calculated and send in a friend that you trust, with cash in hand, to make a low ball offer. Tell him to start low and go 75% of what you are willing to pay, if she bites you get the car cheap, if not go back and start your negotiation at 60% and work your way up. That way she will have already been offended by a lower than expected offer, and even if she won't come off the car for what you are willing to pay, she has your number and highest offer. Remember that the economy sucks, and things aren’t selling the way they once did. I would get the shill buyer to start around $500.00, based on the pics. Good Luck! looks like a solid starting point car.

So I have been searching threads and trying every suggestion and idea to get rid of the front end shimmy on my 73 240Z, and all I have managed to do is move the speed range at which the steering wheel vibration comes and goes. So last night a friend and I went after the problem with a vengeance. We first took the rotors and wheels off the front and put them on the road force balancer he uses to do his race car tires. This machine is the hooptie, you can spin the tires really fast and then test the balance by applying pressure to the tire as it spins, really cool. Front right was 1/2 oz. out by its self, and 1.25 oz out with the rotor attached. We stripped off the weights and suddenly the wheel was out by 8 oz.'s! We then match balanced the tire to the rim, and the rim to the rotor, and we were back down to a manageable 2.75 oz's which we split the weights 75/25 between the inside and outside of the rim (based on the offset) The wheel spun perfect on the machine. We then repeated the process L/F and did just the wheels and tires on the back. It was late when we finished and I wasn’t going to do the road test with beers in my belly on a Friday night for fear Johnny Law would get his long arms into my life. This morning we got some breakfast, went to his shop and got the car. There was almost no traffic on I-83, and I could go for it, I am proud (and amazed) to say that there is no remnant left of the shimmy all the way up past 105 MPH!!! In fact, the car is smooth as an eel, I let go of the wheel at top speed (didn’t take my hand off, just let go, I'm no idiot) and the car tracked strait and the wheel looked just like the car was sitting still. Thanks to all for the information herein, and remember kids, there is no mechanical problem that can't be fixed, endeavor to persevere. VEVA 240Z !!!!

Crutchfield? Critchfield? Something like that.............

Stumbled across this old thread while doing a search and had to wake it up again. Two of my favorites Quote "If you don't start no sh!t, there wont be none" My dear old dad. Quote "No matter how hot she is or sweet she looks, some guy, some where, is sick of her sh!t" Unknown Genius.

This is all correct, I assumed the stock speaker was an 8 ohm, my bad.

you will need to put a cross over transformer in before the speakers to ballance the impeadence at the output of the radio, works like a splitter if you will. I would also reccommend you replace the original speaker with a new set of speakers to insure the speakers are ballanced as well.

And here I've been spending all this time and money trying to keep my car hooked up to the road. Could have just kept putting cheap tires on the back. Like I said, whats the point.

Don't forget the fourth and fifth things, "I have line locks" and "My daddy is going to buy me new tires for my birthday"......................Phuctard.
