Mrs Mook's HZ Prem

Now here is a tricky problem....
Ambientgoat and I got the prem up and running last night after discovering that the hose from the pickup to the hard line had perished. This was replaced and then the engine could get fule and be started. The car has been sitting 24 hours and now it won't start? We did change the file pump to one without the glass float. I'm sure that the Origenal one was fine but just couldn't suck the fuel through because of the crusty hose.

A lot of the vaccum hoses are very crusty in the engine bay would this make a difference?

Cheers,
Mook


New pump

Plus goat primed the lines 'manually'

There is every chance you have installed the fuel pump cam lever on the underside, meaning the pump isn't pumping. Remove the fuel line from the carby and crank it over and see if any petrol is pumping up the line. If you have had the needle out of the carby make sure it have been re-installed the right way around.

I had it running for ages last night, plus I gave it some decent revs, enough for the missus to complain. So it must be sparking and pumping...

In addition to what innuendo has written (very possible but thought the pump lever on the 6 was a bit short for that to happen....), pop the aircleaner off and have a squizz down the carby throat while giving the throttle linkages a crank over to full throttle a few times. You should see a distinct squirt of fuel enter the venturi from one side. If you don't then one of two things have happened - the accelerator pump plunger rubber (or leather if it is that old) has come adrift off the accelerator pump or possibly the fuel bowl has drained back overnight (not common on these) due to a valve in the fuel pump leaking back (much more common in HQ and early HJ quaddies).

One of the quickest ways to suck fuel up and into a strommy is to remove the aircleaner, hold your hand flat over the top of the carby so it wont suck any air in and get a mate/other to crank the engine over for a short time. You can achieve similar by just using full choke while cranking. I don't recommend the hand over the carby bit if you've seen it backfire a couple of times already....

If it not fuel (ie; the plugs are wet with fuel) and has been sitting for quite some time then likely the points (GB534?) and condensor (GB538?) are most likely a bit average or just plain dirty. Just pop the cap off and make sure that the rotor button turns and there is a very faint blue spark at the points when the engine is cranking. If no turn - the dizzy or the cam gear is stripped (easy but takes a little while to fix either). If no spark, then to get you going suggest use a feeler guage (or even something like thin cardboard or thick paper) to set a gap of around 15 thousands of an inch (about 0.4 of a mm) between the points. They may just need a bit of emery or sand paper between the contact areas just to clean them up a tad first.

Let us know how you go.
