Andy FitzGibbon Posted June 11, 2008 Share Posted June 11, 2008 My '85 EA82 has a Weber DFEV on it now. The car is manual steering, so I could fit a DGEV on easily enough (no issues with choke hitting the PS pump reservoir). I'm wondering if anyone here has driven both carbs, and could comment on performance and fuel economy differences between the two. Do the larger venturis of the DGV carbs make that much difference? Thanks, Andy Quote Link to comment Share on other sites More sharing options...

Thanks, Andy I couldn't tell you about the difference in performance, but I've installed both. The DF version is a mirror image of the DG and I preferred it since the throttle cable was easier to configure with the DFV. Performance wise it didn't make a noticeable difference on my two Brats.

bigjim5551212 Posted June 17, 2008 Share Posted June 17, 2008 The performance difference is not that much. Here are a couple comments. 1) the throttle shaft on the DGAV DGV series can be repaired with a bearing kit, so there is no slop, the DFAV series can not 2)The air horn is the major thing thats larger on the DGV series. The air horn on the DFAV series is smaller. The venturies are the same, 26 and 27 mm, and the opening on the bottom of the carb is 32 and 36 3) The linkage is reversed between the 2 carbs Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted June 22, 2008 Share Posted June 22, 2008 The venturi's are not always the same size. There's about three sizes. The DFV's were used on many OEM vehicles and usually have a lot of extra stuff on them. GD Quote Link to comment Share on other sites More sharing options...
Andy FitzGibbon Posted June 23, 2008 Author Share Posted June 23, 2008 Thanks for the replies- sounds like I should just stick with what I have. Andy Quote Link to comment Share on other sites More sharing options...
