Hi All
Just some advice from anyone who has had to change the front axle ball joints on a Dana 30 axle on the XJs  I had my mot yesterday and was given an advisory to replace the front top ball joints as they showed signs if wear.
I assume its best to change both upper and lower at the same time but i wanted to know from anybody whos done this job before if its worth the extra cost off buy aftermarket HD joints vrom the states or just sticking with the factory Dana or Spicer made joints available over here.
Any recommendations would be appreciated.

at least you have a genuine knowledgeable answer, i assume its a one piece gasket, as the individual ones require the end plates modifying.

you gain nothing from individual gaskets as the gaskets are covered by adjacent heads, so when you remove one you disturb the head next to it

Cheers Dave, they're the lads who sent me the thicker gasket by mistake, they say it doesn't make any difference.

As you have probably guessed the one hole and two hole identifiers mean different thicknesses in the gasket. Technically yes you can use it but will it cause an issue with running......possibly.

for the correct answer give these guys a ring on Tel: +44 (0)1246 455350

They will give you a definitive answer advice for the task your taking on

Hi
Just looking for a bit of info, my jeep cherokee has a cylinder gasket with the two hole indicator on it , I have purchased a new gasket but the supplier has sent me, a gasket with the one hole indicator on it,( I had asked for the two hole one). is it ok to use this instead? id appreciate any info.

I have listed all of Birtys 2023 events in the jeeptrek calendar, but they appear at the moment just as a text entry. I would like to use a logo graphic for Birtys if there is one available to use with permission. I need an image file that is anything between 300x300 and 500x500 pixels, square or rectangular. Can someone in management get in contact with me. Cheers.

I run a 36/36 webber on mine and the setup process is the same for a 32/36.

Bottom line is if the idel isn't correct, no matter what you do it wont run right. These surprisingly are very simple to setup and people often over complicate the process.
Base setting is mixture screw turned out to the point of idle increases then decreases, to a maximum of 1 1/2 turns out. any more then you need to increase the idle jet size.

the link below takes you to the weber setup instructions (Redline is the manufacturer).

Once the idel is set then the jeep will run with no issues, if the jeep is then hesitant on full throttle or delay in pickup then an increase in main jet maybe required.
Fuel pressure is also a key point and swapping to a 12v fuel pump capable of giving 7psi constant pressure (bypass may require installing for a return to tank for over pressure), anything less and you could see fuel starvation. A mechanical pump is fine but you have to rely on cranking speed for fuel delivery, whereas a 12v pump its there straight away (personal preference i think)

from my days playing with Escorts and Capris the float should be parallel to the top plate when held vertically as a good rough starting point, and check the pump jet diaphragm is working correctly, doesn't have a blocked secondary choke nozzle.

Hello all, anyone here got experience of the weber carb conversion on the 4.2l engine?  basically my jeep starts idles and runs fine - until you try to open the second choke. it gasps and stutters then pulls through, but not very well and with not much power.
I'm guessing its a setup issue with not enough fuel coming through - does anyone know a decent set up for these carbs or anyone who might be able to help me tune it - carbs seem a bit of a dying art these days...
it also has the issue that on a steep gradient it stumbles and stalls. So I'm guessing float level isn't correct which also could be related to the flat spot issue  - but once again getting correct info on this seems difficult with many conflicting comments on the web...
cheers
