    Trying to measure off the photo it looks closer to 10-24 than 10-32.

    Too small and too high revving – be okay in a bug.

    They rotate the right way but they're quite small capacity 1186 to 1490 in 8 valve form and up to 1712 in 16V. Typically very revvy but durable.

  4. Met a French chap at Superfest back in '18 held at Le Mans who raced a Bug with one in, it went like Marmite off a shovel.

    I'm sure you're right but that wouldn't have stopped someone doing it anyway!
    I read about people fitting golf tdi diesels but having had one that was ace in a golf, I also towed two dinghies with two youths in the back it and it wasn't all that when it had work to do.

    @scrooge95 - get your squinting glasses on and count them ;)!

    Actually, there was an 8v 1700 in the unloved Alfa 33 with 117 bhp at 5800rpm and 112 lb.ft. torque at 3500rpm. I'm sure that would make a perfectly acceptable engine in a T2.

    On it like a bonnet ;)

    (You do realise that I don’t actually keep the carbs in the kitchen, right?!)

    Braving the rain again, out to the garage…….

    I appreciate there’s not an inch of thread in view, but I’d say there looks to be 2 threads per 1/16… ie 32 per inch

    People do strange things just because they can.

    Your nut is a perfect example of what happens when you
    a) use a metric spanner on an imperial nut
    AND
    b) get mixed up about which one is RH thread and which is LH.
     
  13. Pretty gruesome, but not Ms Scrooge’s doing…

    Bit battered, isn't it?
    At least I can say 'it weren't me' ;)

  15. Bodgers are everywhere. Be vigilant.

    My fave is folk who undo the screws on carbs with the narrowest screwdriver they can find rather than walk ten feet across the garage to find a bigger one, thus chewing up the slots for later generations.

    These people should be shot. Harsh, I know, but these things must be done.

    Do you think that @paulcalf 's carbs have had metric M5 turnbuckles and rod ends, ah hem, 'modified' to suit the carbs and CB linkage?
     
  17. By modified, you mean bodged?

    Surely not, who would do such a thing? Paul paid good money for them.
    Seriously for a moment, there's always going to be some interface between the US imperial linkage and the Italian metric carb. Someone may have decided to move that transition.

    I saw a couple of Alfa engines in bugs back in the 80s. I thought it was a thing back then like Subaru are now.

    I didn't even know VWs were a thing back then - I was into squatting, hedonism, illegal drugs and playing in bands. :)
