    Hi. We're considering having our 43 year old twin Solex carbies replaced on our 2lt Kombi with Webbers after hearing good things about them. Can anyone tell us more about doing this, your experience with them, and do you know if it can be a straight replacement? We've heard conflicting advice about needing internal engine modifications to accommodate the Webbers?? Thanks!

    Can't help re Weber's but a properly reconditioned set of solex assisted by a good record vac dissy work well.
    Don't use a worn set as a guide.
    Vw king.( Andrew) is recommended go to for this.

    An option that will cost less than the weber swap.

    I prefer Dellorto DRLA 40's over Weber IDF 40's. Mainly because they take a larger idle over Weber IDFs

    I would also be buying rebuilt Italian carbs as a first choice. Alfa1750 on eBay is your man.

    New Spanish Webers next.

    Personally I don't like the HPMX and other IDF copies out there.

    Get a quality linkage as well. CSP Bell linkage is my preference. Aluminium hex bar are a waste of time.

    I would also learn about jetting carbs. Otherwise you will be paying $$$ to set them out.
    Especially the Chinese copies are no where near the right set up.

    Thanks. Yeah that’s our other option to have the Solex overhauled. I’ve been quoted about half the coast of new Spanish Webbers, so doing our research on both options.

    Good advice provided and budget you have may be decider and consider standard engine and standard carbs (with a complete overhaul) could cause less issues overall for you.

    I have run two engines with Dual Kadrons on them. They are brilliant too.
    So another option depending on what you can get and what price.

    I don't know enough about them internally to be much help but I will say that a good linkage is worth the money. You want a nice solid bar and connection points so everything opens and closes perfectly.

    Well I have the Gen3 40 HPMX carbs on my kombi and have finally got them dialled in and they are better than the Italian 40 IDF carbs that I took off.

    I run the CSP bell crank linkage but it involves re-routing the accelerator cable.

    I think if your engine is stock then stick with the stock carbs. If you have bigger valve heads, increased bore, free flowing exhaust then you can consider a carb upgrade as part of a package.

    Keep in mind that the Solex will give the best overall start up, warm up and economy.

    Let me know if per chance you are considering a RPR 40mm IDF Carb Kit, as I'll probably be selling one. They are probably Chinese, but made to the specifications of and recommended by Rod Penrose Racing. Have been jetted and had a manifold tapped as appropriate.

    They have been bolted on, but not fired up and as such are unused and completely brand new.
    I'm expecting I won't need them as I'm now looking into doing a complete engine rebuild/upgrade and in doing this I'll probably change over to EFI with a full on Haltech engine management system and as such I won't need Carbs at all.

    Not looking to make my money back and happy to sell for a good price if you want to try something alternate to Webbers at significantly less cost. I paid full price, but they won't be worth anything to me if I switch over to EFI and as such I'm happy to move them on cheaply to another KC member if you just want to give them a go (i.e. and significantly limit your loss if they don't end up being what you want).

    Send me a PM if interested. I'm in Sutherland so delivery is not an issue.

    Cheers

    P.S. Mods - Apologies if not considered totally relevant and please delete if not appropriate.
    Didn't post in "For Sale" section as I'm not selling yet and I only raised it here as RPR is prob a 30min drive from this KC member and as such will probably come up in her search for options.

    I advise both!

    Stockies are perfect for a stock to mild motor. It really also depends on driveability and fuel economy you want too.... like ..... fuel economy.....and.... starting on cold days... tuning consistency...etc.
