daveyc123 134 Report post Posted October 26, 2018 Hi guys, does anybody know if the Weber dcd carb and a Weber 32/36 dgv carb have the same mounting face that attaches to the inlet? I am looking for a manifold to fit a 32/36 and have been offered one that fits a dcd twin choke. Just wanting to know if this will work. Cheers Quote Share this post Link to post Share on other sites
azzurro 4,790 Report post Posted October 26, 2018 Pretty sure the bolt pattern is the same accross all the small downdraft webers so both should bolt up to the fannymould no problem. However actual choke holes may be at different ends and linkages can change around sides and rotation directions and the dcd will be taller than the newer dgv (and a different top) so more likely to have linkage and filter dramas than manifold fit problems Quote Share this post Link to post Share on other sites

daveyc123 134 Report post Posted October 26, 2018 Thank you! Basically I have a dgv carb fitted to my 1256 viva. The manifold was home made by the previous owner and with the carb and filter on it fouls the bonnet. So I have been looking for a replacement manifold. One has poped up, but says it fits a dcd Weber. So it should work? Quote Share this post Link to post Share on other sites

vivaspeed 18,600 Report post Posted October 26, 2018 I'm pretty sure they are interchangeable. What's the jetting in the 32/36 because they were used on much larger engines. I ran a 28/36 DCD with too large jets and it was terrible but tune it down smaller and it was fine. You can also take a SPI injection unit off a Falcon and it pretty much bolts up too (with some slight slotting) In case you want to run EFI with massive injectors at 0.05% duty cycle 1 Quote Share this post Link to post Share on other sites
yoeddynz 18,397 Report post Posted October 27, 2018 Yeah 28/32 would be more than enough on a 1256 me reckons. Quote Share this post Link to post Share on other sites
daveyc123 134 Report post Posted October 28, 2018 The carb was fitted prior to my ownership. I have no idea what jets are in the carb. It idles nicely and starts easily. But I haven't driven it yet, it's been a work in progress for two years! Is there an easy way to find out the size of the jets? Quote Share this post Link to post Share on other sites
azzurro 4,790 Report post Posted October 28, 2018 Yep. Take the top off and have a look. If your gonna do that may as well give it a brakleen rebuild. Get an exloded diagram. Watch a carb dissembly video. Take notes/photos and be clean and organised. No extra parts on reassembly = win 1 Quote Share this post Link to post Share on other sites
