So, playing with the fuel system and WUR

System and control pressure are within specs.

I adjusted the air valve idle mixture screw with a spare injector, per the WSM.

pulled the plugs and spun the motor to make sure no excess fuel was present in the cylinders.

Now, I have a no start condition. ?Engine will start with no starting fluid, butdies quickly


What could I have overlooked?

Thanks for this. ?Not great news for me, as it means I have to rebuild mine. ?The top port will not hold vacuum.

Michael,

Would you have an 063?

One of my big questions at the moment concerns the vacuum ports. ?

i know they switched functions over the years, but I dont know which of my ports is supposed to hold vacuum, as opposed to being vented

I did manage to find the temp vs pressure curve

Re: WUR questions

 

Nothing that ends in 063.? Maybe look at cross reference parts.

I used to run adapters and fuel lines from the car to a bench test.? That way I could test and calibrate them.? Used to sell them on Ebay.

The lower port will lower pressure with vacuum and raise pressure with boost (forced induction)
The upper port (near fuel lines) will raise pressure under vacuum, and lower pressure with boost.?

Lower WUR pressure = richer. Higher WUR pressure = leaner.?

You should have a vacuum diagram on the underside of your hood which will tell you which port should be connected to which.?
However, under vacuum you want it to raise the pressure so when vacuum is removed it gets richer for better response. So top port is where the vacuum is likely to be. Lower port is unlikely to be used, but if it is, it would likely be connected to the same port for vacuum advance or to receive partial vacuum during accel. It won't be connected to manifold vacuum.?

Re: WUR questions

 

I know nothing about the CIS system, but I bought a kit recently to test my L-jet fuel system. It appears to have the 10mm fittings you need?



Good luck!

WUR questions

 

Keeping on with my CIS testing. ?I have a 79 with a 063 WUR. ?The WUR was rebuilt 6 years ago, and has 4,000 miles on it.

I had assumed that the top vacuum port on the WUR was supposed to hold vacuum, and that the lower port was to be vented. ?In my case, the top port is connected to the right side of the TB, while the lower port is connected to the rear of the TB

But the top port does not hold vacuum, while the lower one does.

Also, I went to go check my control and system pressures. ?My kit came fitted with M12x1.5 inverted flare fittings. ?But the hard line on the WUR has 10x1 fittings, both in the body side and the flare side.

Any idea where I could find an adapter?

Cheers
