34 ICT

Hi all,

I have been very lucky this week to find a new weber 34 ICT for my Beddy.

It was listed for a 2.3 but I have a 2.0 so will it need the main jet need changing or can I just bolt it straight on ? If it needs changing what size do I need ?

I have the Haynes manual for it which gives no real info.

The No.'s on the carb are : -

9104626E
87 43

Any help would be fantastic.

Regards.
Paul.

Hi Blue,

Thanks for that info, it will be most helpful setting it up. I've also got a 2nd hand carb I'm refurbishing.

Best regards.
Paul.

Just taken old carb off and I'm wondering if I have some sort of ICT/ICH hybrid on there ?

Seems I have the electric cut off valve but also have 3 fuel pipes connected ???

I have two on the end and another one going to the side so I think someone could have possibly kept the bottom half of the carb (ICT) and possibly fitted s ICH top half (just a guess). So would it be possible to blank those two pipes off and just have the single incoming ?

Have got pics but file too large.

Cheers.

Hi Paul,
Good score on finding a brand new 34ICT.
What year is your Bedford? If you have the Bedford (Isuzu) Midi 2.0l engine it may have had had a twin choke originally and somebody converted it to the one fitted now. That could be a 2.25l Land Rover ICT carb. One fuel line maybe a return. Are all 3 lines connected on your engine, if so where do they go? How many to fuel pump or even return to tank?
If you're fitting the new 34ICT you may need to get a smaller main jet if it ends up running too rich and starts being lumpy. For the idle you may just weaken the mixture enough by turning the mixture screw in.
You could contact Webcon or Eurocarb to see what sizes are available, they may even have a chart with standard 2.0l jetting if they were fitted as replacements.

Hi Frank. It's a 1984 CF2 2.0 so should be an Opel engine. Not had chance to track other pipe work back.

I know it's the Opel engine, same as in the Ascona etc, but with different carburation. I thought the Midi engine is the same, but it's an Isuzu engine only used in the later, smaller Bedford vans.

Looks like the difference is the top half, 2.0l had the 3 in/outlets.
Since it's only the lower part of the carbs which wear, i.e. throttle shaft, I'd use the top of your old carb, clean it thoroughly and swap the needle valve if it's the same size. If it's smaller, you can get a new one in the right size from Eurocarb. Then just take the idle and main jets out to check the sizes and if they are the same leave them, if not use your old carbs jets. Clean them with carb cleaner whilst you got them out.

One pipe to going to the side of the carb has been cut so just hangs freely. Another goes to a gizmo underneath the engine which I assume is a mechanical fuel pump as petrol came from that side. I couldn't trace the other all the way back but it was going a long the chassis so that's probably RTT.

Hopefully it's just a case of getting the right air corrector and main jet replaced.

Hi Frank, thanks for the info. I didn't realise there were other versions of the ICT carb tbh. The one I bought off ebay was listed for 2.3 so I thought it was just a case of changing jets etc. I didn't realise there was more pipe work on my carb. Doesn't explain why one of the pipes is cut (?) or is it just for venting ?

The van had been running like a bag of nails and the only way I could drive around was to increase the richness mixture and turn down the tickover.

When you have the tops off, have a look what the 3rd take off is. The inlet & return will be before the needle valve, to control how much fuel goes into the fuel bowl.
If the 3rd take off is just an open connection, it could be a breather take off and may have been connected to the airfilter or part of the crankcase ventilation system (early emmissions control).
Check whether the hose has been blocked off with a plug/stud/bolt.

Weber used to make the same basic carb version, i.e. 34ICT, 38DGAS, 45DCOE etc and then jetted them for a particular car model/engine with special fittings/modifications as required. You'll always find another number after the carb model stamped on the carb flange, which indicates the car it was made for. For example the 45 DCOE 9 had different sized choke to the 45 DCOE 13 and one was used for Mini Coopers, the other for tuned MGB's.
38DGAS were fitted to V6 Capris and Granadas, but had different jettings.

Hi Frank, thank you greatly for your help and advice. I think I will do as you say and split the carbs using the top off the old one. I checked the main jet at work from the old carb and it's a 150 as stated in Haynes so now I will know what size other parts to replace.

What does seem odd is the incoming fuel pipe to the carb is connected to the opposite side to the carbs that have just the one single fuel inlet and I'm wondering if it's been connected to the wrong side on my van ? would it make a difference ?

The vent pipe just runs off down the side of the engine and wasn't connected to anything so I will get back underneath and take another look.

Thanks again.
