I am surprised we are all not speaking with a pommy accent. I'm surprised so many poms are migrating to Perth Western Oz, where it never rains.

Hell if they came to Queensland, apart from the temperature, they would feel right at home.

We've had 26 inches of rain, so far this year. There have been only 10 days in the last 50 when there has not been at least a couple of mils in the rain gauge.

I expected to have at least another thousand or more Km on the 7s new motor by now, but it has not been the weather to subject it's shinny new paint to.

It is going like a train, particularly between 80 & 130 Km/H, [50 to about 80MPH], & I absolutely love it, but boy has it developed a thirst. It's doing less than 20MPG.

I get the impression it is bordering on flooding, so when I can get it out of the shed, [into enough light for me to see], without getting wet, I'll check the fuel pressure.

I have a minor problem with the rear carb main jet staying down, when the choke has been used & pushed off. It only takes a touch to make it pop up, & the rough idle when I'm shutting the gate tells me it has stayed down, but it's anoying. I have never had to lubricate them, & these are over 60,000Km old, so should not be tight.

Anyone ever lubricated the main jet, & if so, what did you use that survives in that constant petrol area?

Graphite?

I've had this problem and what I found on my car was the 'flexible' tube that feeds the fuel to the bottom of the jet had gone less flexible, so I replaced both jets and went for the non-waxstat type, which are meant to be better as well.

Cheers,
Dave

Good thinking Odd. I used to have a "puff" bottle of graphite powder for this type of thing, but it's so long since I used it I wonder if it's still around.

Here's a hint on the poor gas mileage. On my elderly Z-S carburetors with over 160,000 miles, the inlet needle valves finally gave up the ghost failing to shut off the incoming fuel. This resulted in an over rich mixture. Replacing them solved the problem and restored the gas mileage back to the upper twenties.

Not knowing which flavor of carburetor you have, perhaps a check of the inlet valve may be worth while. You'll know your inlet valve has failed if the pressure to the float bowl is correct, yet the float bowl is over full as you remove it from the carburetor body.

For those amongst us with Z-S units, there are photo articles around here someplace for your convenient entertainment.

Thanks for the input Mildred. My carbs are SUs, & the float chamber valves are reasonably new. Probably 4 years or so old, but with only about 15,000Km on them.

I do think it is a flooding problem, as during the problem with the new water pump there was an occasional smell of petrol, when running.

With my old engine I had corrected the fuel pump pressure by adding packing between the fuel pump & the block. This was a few thicknesses of cornflakes packet, cut to shape. I am fairly sure the mechanic who rebuilt my engine would have discarded my carefully selected packing, as not befitting his professional standing.

A friend has a good quality pressure gauge which reads low enough to suit testing my fuel pressure, but he is 30Km away, & with our constant rain, & the Capri requiring some attention, I have not managed to get there.

OK, I've been slack, & will get off my backside, & look after my little lady as she deserves, ASAP, promise. Meanwhile I am enjoying how hard she is going, & hang the cost.

Finally got a pressure gauge in the fuel line today.

The thing is running 4PSI, no wonder it's flooding.

A mate, who can still see checked for me & found there is no spacer under the fuel pump at all. The whole lot must have gone missing during the rebuild. I have a couple of mates who are likely to have some spacers stashed away, looking for one for me.

Meanwhile it started to rain again, & as I do this work out beside the shed, where there is much more light, I had to put the car away, & did not get to look at the main jet. How old were the ones with the tube gone Hard Dave. These are only about 10 years old, but I'll check them next time.

Meanwhile in the last couple of hundred Kilometers she has used 10L/100Km, or 28.5 MPG. This is a big improvement, but I used to get over 30 in my local country running, so I'll keep at it.
