it Idles sometimes but not allways, conks out when I stop / pull up at the lights, and back fires when I back off the accelerator.. I have checked the distributor / dizzy / all that kind of stuff and its all good... I'm thinking something in the carby is gone? it still goes hard but yeah...
any ideas as to what else it would be?
Cheers for the help fellas

Sounds like shit in your idle jet, try swapping leads 1 and 4 or 2 and 3. Run the car till it back fires a few times, swap them back and see if it fixes it. If it does you should probably pull the carby down and clean it all out or it will more than likely happen again.

Also run a timing light over it. Belt may have skipped a tooth.

Sounds fuel related. Could defiantly be a blocked idle jet or a vacuum hose come off/cracked.

skipped tooth would give symptoms 100% of time and would have power loss.

mmm had a similar issue a month ago...Stop at lights and it would stall, running rough, then would run perfect..I didnt have it backfire however -I checked and paid out to replace everything I could think of...took it to an old school mechanic and it turned out to be a massive amount of crap in the fuel tank being pushed in to the carby ...damaged the carby so i smashed on a 180 holley - works a dream

ok so we're thinking that its probably the idle jets that are blocked as stated above ^^ where abouts are the idle jets and how do I get to them?

not trying to be rude or anything but my advice with carbys if u do not know what ur doing dont touch them send them in for proper cleaning u could run some additive in your fuel that may clean it out though it may cost a few hundred but atleast u know its done right im sure the boys on here know a carby specialist near u

Firstly try one of the normal methods... Either swap the leads so it backfires as stated, or take the airbox off the carby, give it a good rev then cover the throat with a rag, which hopefully will suck out any crap in the jets.
If this does fix it, it doesn't necessarily mean you need to strip it and clean it, but it may be worth figuring out where it came from. A small inline fuel filter between the pump and carby won't hurt either...

Ok so we've swapped the leads and back fired it about 10 times, we tried to suck the crap out by covering the air intake (made it choke three times by doing that) and neither of those methods made any difference. We checked all the leads / spark plugs and they'r all good.. :/
Thinking of taking it to B and P car care at Everton hills to get them to sort it for me.. unless anyone has any better ideas / wants to volunteer to fix it for a 6 pack or a few $$...
I just want to be able to drive my carrrrr  lol

I think this might show you where the jets are and how to get them out... I just hate his voice so I'm not watching it again...

Get a carb kit and take it slowly. You could check to see its not flooding either, sometimes fuel starving symptons are in fact over fuelling

Yeah that's what the guys at my local mechanic quoted me, but they were going to send it away to get rebuilt and it was going to take ages... At least the guys i went to did it themselves and it was ready the next day
I really didn't want to spend $400 on it, but after waiting around for a good 6 weeks hoping that a 2nd hand one would turn up in good running order (good luck with that  ) I decided to just bite the bullet and get it done.. And I'm glad i did. In the end it's worth spending a little bit extra to know that it's all being done properly
