   I need a towel! I'll let you know how they get on. I need a good source to get some extractors and tail pipe made and or bought. Any suggestions would be much appreciated. |

As suggested on OS, try pitstop items. May have luck otherwise I guess you'll need to hunt down someone to make up some. Might even be worth trying afew GM wreckers that deal with old shuvs or vivas as I'd say there will be afew around that were modded back in the day.
Those carbs and that intake looks so hot. I couldn't imagine a more suitable setup for a 1256 aye. Looks perfect while still being shiity fuucken Su's haha

Stromberg CDs, not SUs  Nice score, laddie, haven't seen a pair for a couple of decades - just got to go through the soul destroying getting the needles sorted to suit. If you check out the posts I gave you links to in your tuning thread, you'll see what I did - worked well, too. Have you checked out the UK Chevette forum(s)? This is one a few of us are members off - www.chevettes.com/forum/ . They were getting a few people together to have some extractors made. |

They were tuned before they were taken off so they're all good. Fired them up tonight and it fired pretty much straight away until I noticed petrol pissing out of the rear carby! I'm kinda lost now but I'm assuming that the float or something similar isn't working on that carb and simply letting petrol coming flowing in? Check the picture for where petrol is coming out....  It's the rear carbyy brass or copper looking pipe with a hole right through it. Perhaps it's an overflow? |

Been a while since I had one apart, and as I've long lost my Stromberg manual, overflow - or rather breather tube - is as good a guess as any.
As I expect they've been sitting for a while, it's quite likely they're a bit gummed up and/or there may be a bit of debris stuck in the float valve.
For the money, it may be a good idea to pick up a couple of overhaul kits and rebuild them. That way you KNOW they're correctly set and ready for use.
A fuel fire isn't really worth taking the risk, IMO.
Going by the mixture adjustment screw, they're a bit older than the Chevette, anyway. Do they have any ID on them? They 'may' be 1 1/4 (125) rather than 1 1/2 (150) the Chevette stock size.

Thanks everyone. As I suspected it was the float. More to the point the circlip holding the float hinge in place had gone awol. Put a new one in and it's all good. Cept for the part where the heater pipe coming out of the head snapped off from the head  It was getting old and was under some pressure due to the new inlet being really close to it. That'll learn me. Now I have to remove what's left in the head (god knows how) tried screwedrive and hammer to see if I could it started but no go. Any good tools or methods would be much appreciated. |

Is the pipe cast into the head, or jsut pushed or screwed in?
Could you not just chop the pipe off flush with the head and tap a thead into the head so you can screw in a new outlet?

It's already tapped into the head but it's left about 5-10 mm worth in there. I'll keep trying to get it out but it's been in there for 30 odd years!

You might need to drill it out larger and then tap a new thread. That's going to be one mighty big drill bit!!!

I've got an engineer mate coming round tonight. It pays to have good mates  Can't wait to test drive the thing after putting the carbs on! |

ok, a tapered drill bit looking thing with square on the end called an easy out was the trick. He's building me a whole new stainless bit tomorrow. I knew there was a tool for everything.

Ur way duz sound betta tho!! |

Sunday night update. My mate brought back my original heat pipe somewhat shortened and a new stainless badboy, it appears the thread is tapered as he said it was a strange thread.
Anyhoo, got it all back together and fired it up. Doesn't idle without the choke on and pretty much runs like a dog without it on too. Sealed the brake booster pipe better and made sure the vacuum advance was sucking too.
Took it for a test drive and my god...while the choke is on and it's kinda running it goes quite a bit better and has that lovely induction sound when gunning.
I think i may have to send the car into a carby specialists to get them tuned. I messed around with a few settings but I'm really pissing in the wind. I'm hoping it doesn't cost heaps.
Now just waiting for my 13x7 minilites to turn up!
