| | The 34ICH uses an alloy adaptor ring on the top and this usually, I think, comes with the kits. If you use that, the standard late filter housing fits perfectly. The same ring fits all of the ICH sizes, 25-27-29. FastRoad etc should have them if you don't have. |  |

| Man, it's been a while.
I got the 34 ICH mounted, but I've now been confronted with another dilemma.
The old exhaust pipe for the car was mostly rusted out, and I'd like to replace it with some new stuff. The problem is, I don't know whether to upgrade it to 2 inch, like I've seen a couple guys do, or simply replace it with 1 inch? | |

| Really hard to start. Then it'd only idle with choke out. Obviously wasn't getting any fuel through the idle circuit so I removed the idle jet and the mixture screw and blew it out using a tyre pump. Put it back together and no change. Removed the idle jet, pumped more air through it and noticed some air/fuel coming out of a hole just above the idle jet. On the inlet manifold I found a little brass plug that fitted the hole. For some reason the Weber 34 ICH has a hole just above the mixture screw with a brass plug in it. I was lucky it only blew (or fell) as far as the manifold. I'd imagine an air line could blow it far far away, so I'd suggest putting some tape over it before blowing through to clear blockages. I still don't know whether it fell out and that was the original problem or whether I blew it out but either way, when I put the brass plug back in the hole it all works fine.

| Hi folks having read this thread with interest I hope someone might know the answer to our issues. On the yellow 95 project (sorry no photos still!) we have a Weber 34ich. It has a 27 stamped on the body which I presume is the right one.Having fitted a kit the accelerator pump still doesn’t work manually or on the car. Float chamber seems to fill properly, the suspects are the small jet at the bottom of the float chamber and the pipe in the casting to the pump. Can they be cleared with air or manually? Is the brass plug the one referred to in a previous post on this pipe?

| I know nothing about ICHs, but please do not try to clean jets with a piece of wire or a needle or you'll ruin the bore; only use compressed air/ carb cleaner/ ultrasonic bath.

| | Thanks the comment Melle here and in the other place. The engine now runs and we beginning to go through the things that will hopefully get it running smoothly. May take a while but as you say we are learning as we go. | |

| Hi all, I disassembled my solex carb today and put all the bits in my newly purchased ultrasonic cleaner.
Came up a treat , and after a (very) frustrating afternoon putting it all back together and tweaking it, my 67 V4 now runs and idles properly for the first time in years.
If only I could drive somewhere other than Sainsbury’s in Bath to test it out,..

| I've received a new Weber 34ICH from Southern Carbs (in Crawley) which is a 'Nick Senecal' kit, which I plan to fit this weekend.
Apparently the idle jet in this is a "47", whereas the consensus on here seems to be to go for a "60". I know very little about carbs and jets, but the difference in those numbers sounds big to me.
I was thinking: Do you gents recommend buying a few different sizes and trying them out (they seem to be only a few quid), or just see how I get on with the 47?

| Hello Mark,
I had a look at a few outlets selling the Weber 34 ICH for the V4. There seems to be a difference of opinion with some saying 50 idle and others either side of that.
I am too new to the V4 to assist greatly but from experience, I have used and consulted with Anthony at Fast Road Cars regarding Weber carbs on various classics.
Thankfully as you say, advice from here will be absolutely spot-on.
I'm currently running a 34 ICH, but that will be swapped when the engine is modified and a 32/36 DGV is fitted. I will be interested to find out what my idle jet is, now that you have mentioned this !!
Good luck.
Richard. | |

| | Jetting can be affected by what exhaust system you have fitted. Both the idle and main jets can often be beneficially changed if you have a Jetex/Simons system rather than a standard one. Go back to page 1 of this thread and have a good read. There are 6 pages for 34ICH issues and fitting tips. |

| Air filters can make a huge difference too. The cheap pancake or lunch box type "sports" or "performance" filters you often see on Webers may sound cool if that's what rocks your boat, they are usually particularly restrictive, which necessitates smaller jets. Not only are they restrictive, they're often also grossly under-dimensioned. Plain old paper filters in an adapted stock housing or a correctly sized and well-maintained K&N filter are a much better bet. John Passini's Weber books are very informative on carburation principles and carb tuning.

| My son and I fitted the weber kit, turned the key, watched the fuel filter fill, then to our delight the engine fired straight up.
We then let it warm up, and started trying to fine tune it. My summary of this : it ran well as soon as it started, and the adjustment screw made almost no difference. I couldn't make it go 'out of tune', back it off, find a sweet spot, or any of that fettling. It just ran, drove fine, and that was it. It may be that it was running slightly better at 'half a turn out', but I might be imagining it. I was seeing vapour from the exhaust even when warmed up, but it was a couple of degrees above zero outside.
The choke/idle 'coathanger' connection fouls on the brake vacuum slightly, which stopped the choke opening fully on its own (i gave it a helping hand during tuning).
The kit comes with a small pancake filter. It seems okay. It's washable....not foam.
Any ideas of what to do with the right hand oil breather? I'm thinking of modifying the pancake to accept it (using a forstner bit drill and some metal tube glued in place).
