    webers

    i know dcoe's are more of a prelude thing but can u put a 40 in an accord or do you need an adaptor plate or manifold to do it?
    what about a 38mm? could that work maybe?
    its not how fast you go, its how fast you get going.

    smaller carbs will work but then you may lose some top end... most cases you'll need a custom manifold.

    Your best bet without going for a new or used 38mm downdraft would be to get a single 38mm sidedraft... someone on here has one that is kinda extra.
    They bought 3 carbs (solexes I believe), so you could use one of the carbs and then buy an adapter that will allow you to mount a sidedraft carb to a downdraft base... I think it's only for a 45mm to a 32/36 base... but I'm not sure.

    you'll probably want the KC 172 since that will give you the most mounting options and more clearance for velocity stacks and air cleaners.

    You may also need the 32/36 adapter plate for that to mount on... or you can find a way to drill new holes to mount it directly to the manifold without the DGV adapter being used. I would port your intake manifold really good. https://www.3geez.com/showthread.php?t=30234
    Don't port as wide as I did... just enough to match the inside edge of the gasket they give you with the DCOE adapter... the important bit to get rid of is the center divider that seperates the primary and secondary barrels.

    Or you can go crazy with the KC 190 and face the carb barrels forward... cut a hole in the hood and have ram air.

    for a single dcoe i would go with atleast 45mm, 48 or a 50mm would be even better but i don't think they will fit and if you have any type of emissions forget it

    It would be nice but this 40mm should be relatively cheap cheap cheap since it was bought at a low price. Plus it's extra...

    nothings wrong with the 32/36. it's just a small carb so you won't get max power in the higher rpms.

    I saw a 40mm downdraft. new webers are expensive... get a 38mm dowdraft on ebay or something ceap so you wont need so many adapter plates.

    Depends really on how much you plan to modify your motor.

    if i bought the 38mm i'd need an adaptor for the 32/36 and then another one for the weber to the manifold... i saw some DCOE's on ebay but thats pretty hardcore for me
    i could jet the 32/36 but by the time i do that i could pretty much have a 38mm bran new

    since i'm talkin about carbs i'm lookin at the vac line removal, whats the easiest approach? remove all the lines, jet controllers, and vac control then put the lines u need in and plug the rest?

    yeah I would remove everything... including the carb if you have a full rebuild kit.

    Buy hew vacuum lines and get to work.

    keep the vacuum secondary.
