All done. I ordered a new one from Burlen. Approx £1+postage The old one did not want to come out, so was lightly drilled with a 6mm bit until it span and was able to pull out. New pipe arrived - didn't think to ask for the olive though, so - where do you get a 6mm brass olive from then? Well, lucki...

SU HIF6 Fuel Inlet Port Leak

Hello all. I have a slight leak from the union on my N/S carb on my 3.5 Rover. I have tried applying some PTFE tape, but that hasn't made any difference. So, how hard is it to get the whole pipe removed from the casting and replaced? I can't find anything on the Burlen site that helps. It is a FZX 1...

Well, I have found the source of the problem :D A bit of head scratching got me to look at what could be different for No. 2, and there it was in plain sight, the brake vacuum take off. When I removed the hose to the brake booster and put my finger over the hole, I got ignition, on removal, just spa...

I am getting more confused as I go along. :? With 2 Colortunes at idle, no. 8 works fine, but no. 2 just sparks. Give it some throttle and no. 2 starts to work but very intermittently. One thing though is that with the even rocker cover off, there can be seen a large volume of oil flowing up into th...

Thanks for the replies.
I now have a brand new dizzy cap / rotor arm and two colortunes.

When I can get at it in some daylight I will give it a go.

Cheers

I have not noticed it using any oil, the exhaust gas is generally clear.

Have just run it for 15mins or so to set up the carbs, and have got some oil on the No. 2 plug tip.

Not a good sign I guess?

Thanks for the replies. I have removed the N/S carb and checked the setup. One thing I found was that the vacuum advance port was gummed up, whether this makes any real difference I will see. The float setup looks ok, although have not done many miles since it was last off. Ran out of time today to ...

I have just redone the compression test - engine warm - WOT 8 - 132 = 128 - 7 6 - 125 = 123 - 5 4 - 130 = 135 - 3 2 - 130 = 135 - 1 This time No. 2 got hot quickly, but didn't get as hot as the 4, 6, 8 The sparks on removal were now quite sooty, I haven't been for a drive since the weekend though. I...

The plug has smelt of fuel, and have been a bit oily wet. I don't think it is losing water The engine has been in for years afaik, I have had the car for a couple of years but have not had much use out of it so far. I have rewired it and fixed some chassis rust, so it has not had much running this y...

Ok, just done a bit more testing.

No 2 is 13k ohms
No 4 & 6 are 12k ohms

Old plug lead of 10k ohms put on, with a brand new plug and still not firing.
This spark was jumping up to 10mm or so when held to earth.

Single cylinder misfire - 3.5 on SU

Hello, I am after a bit of help. I have a 10A SD1 3.5 on SUs installed in my Land Rover. The problem I have is that No. 2 cylinder is not firing, using a infrared temperature probe shows the exhaust not keeping up with the other cylinders as the engine warms up. I have checked the spark and it is he...
