Good work.

I'm running the Flamethrower coil with the Pertronix ignition (but triples) and I have not gone out to that bigger gap, I think high 30's from memory, if your not happy with what you...

You could swap the No.6 plug to another cylinder and see which ones runs lean, it may just be a off spec plug.

If it stays on 6 then it has got to be either poor spark or poor fuel delivery.
You...

You don't say what carbies you are running?

If it is the standard SU's then generally the front 3 should be very similar and the back 3 should be very similar as each 3 run off a single SU. If one...

They are RB's on the front and RB-R's on the rear. I like the dish on the RB-R's which also give a nicer shape to the spokes

Here are some pics of the RB-R's on the rear

I am running 205/55x16 on 7" wheels on the front of mine with Toyo Proxes R1R's. I think it is a great fit, no clearance issues. The trial fit on the rear I think looks better than the 16x8's with...

I had a similar problem some time ago, prior to fitting my Pertronix ignition, maybe you read the thread, there may be some ideas there or a process to follow.

If you have used POR 15 and have Marine Clean left over use that, I found it worked really well. Make sure you rinse well with water after.

The Nissan part numbers are:-
76837-N4500
76838-N4500

The have 2 screw hols at the top close together (like in your pictire) and one in the centre and a third further down. But the window does...

I was intending to fit 16x7 RB's all round but due to a mix up in stock count by the supplier he offered me 2 16x7 and 2 16x8 for the rear for the same price. They have +4mm offset. The rears were...

I manage to get a ride in the 370. They took 2 S30's up the mountain to shoot that nose to nose picture and some weaving about and fortunately there was 3 from Nissan and their advertising agency and...

Hi

The Auszcar club gathered at alpine resort village of Thredbo in the mountains of New South Wales over the weekend of 20-23 February. A healthy gathering of around 18 Z's from Melbourne,...

In Australia the 260Z, which first came on the market in the second half of 1973 had the lights with the divider and 2 bulbs. There was a white light for the parking light and an orange light for the...

This may help. Below is a scanned page from 1970 Australian Motor Magazine which road tested the first 240Z in early 1970. The picture shows the valve stem below the D in line with one of the spokes....

I always ground the spark plug then you should see the spark jump the plug gap.

Hold the coil lead near ground, if there is a spark therethen coil is OK but if not at the plug there is something...

Check that the Accelerator pump jets are squirting gas into the chokes of the carby's. Use a mirror and light to look down the carby throats while someone flattens the gas pedal for you.

Also make...

Des Hammils book on Webers and Dellortos talks about this probelm and he says it can occur if there is not enough fuel in the emulsion tubes when you transition to the main jet. This could be caused...

I have exactly the same problem with the triple Dellorto's I have recently installed. I have got the idle (or low revs) mixture right and the high revs mixture right after testing various jets and...

Most likely you will see them fitted to cars with non standard air cleaners or SU's replaced by tripple carbs where both do not have a means to recycle the blow by.

Haven't noticed the any fuel...

I know how you feel as I had similar problems a few months back, started but would not rev. There are only 2 things here, spark and fuel.

You say you have spark so I assume this is at the spark...

I recently did my 240 with Dynamat Extreme. Initially I bought 1 bulk pack (9 sheets, 18" x 32"). That did the tunnel (sides, top and under heater core) and all the floor on both sides from the...

The drain plug on the diff has a tapered thread so if it is over tightened it is very difficult to get out. Under normal circumstances you should be able to undo it without dismantling the rear...

Not according to page 121 of my Haynes Manual

A 4 speed 260Z is 3.364, but 4 speed 204 is 3.9

Warren

You did not say if it was a 4 or 5 speed so according to the Haynes manual for a 240Z they are:-

4 speed 5 speed
1 3.549:1 2.957:1
2 2.197:1 ...

You can calculate the RPM for any gear using this formula:-
rpm = (mph * gear ratio * final diff ratio * 88) / circumference of rear tire in feet ie 5.25 feet

Measure the circumference of your...
