Help

Just before we start, know that I know ZERO about carbies....Now my new 5K in my wagon came with a weber off an XF, I assume it's off an XF as it has "XF" written on the automatic choke on the back.

 

Anyways, it was running perfectly, and then the car refused to idle...I checked the manifold...bolts were loose, so tightened them, and it helped but didn't fix it completely, so I replaced the manifold gasket, and it still wouldn't idle...so we moved onto the carby...

 

This is what I have tried...swapping 2 and 3 plug leads to make it backfire out the carby, seems to help a small amount but could be my imagination.

Tried revving engine up and covering carby to attempt to clear it out - Didn't help.

 

Now apparently these carbies have an idle solenoid on the side, this has been removed from mine though and replaced with a bolt....I was advised to remove this and blow compressed air through it...which appeared to have fixed the problem....however after driving it again for a while it stopped idling again...

 

I flogged the ass out of it, and backfired the carby a few times and it now idles smoothly at time, roughly at others and then sometimes refuses to idle sometimes also....I am at the end of my very limited knowledge on the subject, so I am wondering if anyone has any suggestions that I can try myself that will be either cheap/free and also easy enough for a person with no knowledge of carbies to try without ruining the bloody thing before I have to take it to a shop and pay someone some stupid amount of money to make this bastard idle.

 

Oh one more thing...it runs smooth and fine whenever revving...the problem is entirely with idling...although it does feel down on power, which again could be my imagination.

 

Thanks guys

Check the fuel float. Maybe its sticking and fueling up?

Just so we're clear....I don't know how to do shit like that with Carbies.

Playing dumb doesnt work with me. Its a few screws. If you can swap engines....swap broken diffs and gearboxes, you can loosen a few screws and inspect a simple carby to make sure that nothing is jamming and that the needle and seat is sliding easily.

Hey bro it seems that you got an internal problem with the carbi....a needle...vacuum leak....etc....anyway there are too many variables in the equation to know what is your problem.....but you already knew that...Well what I do when I can't find the problem I go back to zero ground...let me explain...you could take it to a shop and pay a couple of large ones just so they can tell you they need to rebuild the carbi since it has internal issues...well before you even do that get a rebuild kit yourself and rebuild the carbi on your on....It is just a matter of taking screws apart and putting them back the same way and of course replace the parts...if by any change you mess something up ...well it was already broken so just stick to plan A ...take it to the shop and the only thing you have spend so far is 25 to 40 US dollars depending on the carb series for the rebuild kit that the mechanic needed anyway to rebuild the carbi....so is a win win situation...and if everything goes smooth you will feel full filled since you did it all by yourself. Anyway check out this web page ...is where I got my carbi and they are great....they got any rebuild kit that you may need and all sorts of good information with instructions, drawings, etc.....let me know if it works......While rebuilding your carbi you may want to check your other systems like timing, ignition,spark wire, plugs, fuel pump, fuel pressure, filters....also it is good to run the timing at the dizzy a little bit high when you got a weber.......I hope the info helped you out.

I have had to replace a few xf floats they Implode especially if used on LPG also there are a few nasty diaphragms in XF carbys that could split or go hard.

I would put the idle solenoid back in and hook it up to ignition power, the wire for the 4k asian should still be there. Is the car running rich? Make sure there are no vacuum leaks. Tried carby or injector cleaner added to the tank? You do have a fuel filter? It could also be the mixture screw, they sometimes vibrate their way out. Most likely you have shit in the primary emulsion tube, which is your idle system. A carby kit sounds like the go, kits are about 30 to 40 bucks and generally take an hour to fit. While the carby is apart, always sit the float in some fuel. Every now and then one gets a crack and then the float don't float. Always set your float down a little, that way you won't have any problems with flooding.

If you have a digital camera, just photograph everything as you pull the carb apart. Reassembly should then be easy.

Don't know if this is at all helpful.

 

I don't think the lack of idle solenoid is the problem as I have been driving the car for a while without it, and it was running fine in the KE20 without it. No vacuum leaks that I can find...Car isn't running rich....I'd say there is shit stuck in somewhere, as it now sometimes idles perfectly, and then next time I pull up somewhere it wont idle at all.

I will have to have a go at pulling it down and cleaning everything I suppose. Thanks

I'm pretty sure it's going to end up being shit stuck in somewhere, as sometimes it's idling fine, next it wont?

I thought the XF weber would be wayyyyyyyyyyyy too big for a 5K to begin with?

[Rolla__Boy]

The KE20 was a Karna car...the 5K has had some work done....not sure what, apparently it has 54rwkw?? Either way, it seems to run perfect with the weber on it

If your sure it is a jet with crap in it Give it a few good scotch Cleans, it will either clear it or Block it altogether.
