  1. The Classic Alfa Romeos
    Good afternoon all I'm afraid I'm a combination of ignorant and frustrated on this Weber Carburetor issue. Having had my 2 new Weber carbs fitted a couple of years ago, it is clear they still aren't quite right. They aren't running smoothly especially at the lower end of the revs. Car is a 1988...

    If anyone is interested in a great pair of 40DCOE 32's to suit a 2000 or 1750 Giulia GTV, please let me know. I have a pair going on Ebay this evening, if anyone from the Forum is interested, they can have first dibs at the start price. They both have had fresh rebuild kits, have no spindle...

    Morning All Now I've got my 2.0L 1988 spider to start, I'm going to put an end to shelling out money on the crappy old Solexs. Apparently the Weber 40s are the carbs to have. I have also been told that: - 138 & 139 are the correct ones - and that 200 are the correct ones Questions: what are...
  4. The Classic Alfa Romeos
    Hi All, I have a problem that I can't figure out on my Weber. The rear carb is fine but on the front carb I am only getting fuel out of one of the accelerator pump jets. I have had it apart and cleaned the jet but the fuel doesn't seem to be getting to the jet in the first place. When I hand...

    Hi everyone I have just joined here, I don't have a Alfa car as such my car that I have bought is a Minari kit car based on a Alfasud, I believe it has an Alfa 33 1500 engine not to sure has hydraulic tappets. It had a fire in the engine and was left with fire extinguisher powder in one of the...
  7. The Classic Alfa Romeos
    What happens if one of the pump jets (including cover, washers, everything) goes missing. It looks like one of them popped itself out and went missing after my last race. Engine was running fine, but later one found a slight fuel leak, at the time had no idea where the fuel was coming from, I...

  10. The Classic Alfa Romeos
    I've planned this as my Christmas holiday job and thought they'd be lots of rebuilds guides but I can't seem to find one (though it may be the sherry!) Does anyone have a link to one? Also what's best to soak/pre clean them with, I found a good Alfabb thread that recommended Pine Sol degreaser...

  14. Tuning & Upgrades
    Hi all I am new to this forum so I hope I am not going over old ground here. I would like help to really understand the operation of IDF fitted to many Alfas, Porsches, VWs and other applications so that others do not have the problems I have had getting these carbs working. In fact I think...
  15. The Classic Alfa Romeos
    Hi all, I'm swapping the Solex carbs out for a set of webers, from a similar aged alfa. Everything is good except that I can't work out where the vacuum advance pipe from the dizzy should go. Any advice please? There are cream/yellow coloured caps on the RHS of both carbs and I wondered if...
  16. South Africa
    Hi everyone I bought a 2.5 V6 156 a few months ago, and I'm very happy with it so far, but it is going to need a service not too long from now. It has supposedly had a cambelt service not too long ago, but I didn't get proof of this, so I might want to get that done just to be safe. It also has...
