A few of us have been watching the tech list "carburetor bruhahaha" going on now for the past many months and have been addressing various aspects of the problem separately. One of the cures proposed by one of the tech list guys with a blown Max (John Baltera?) is that of using a Weber DCOE (sidedraft) carb. That started us speculating among ourselves on the possibility of mounting Weber downdraft carbs on the engine. Information and parts for tuning these carbs are readily available -- and the carbs themselves can be found (used or new) and, if not cheap, are less costly than flatslides.(The dunebuggy guys love these things.) The IDA, IDF and DCNF Weber models seem best suited to this application.The fact that they have accelerator pumps should help eliminate the flatspot characteristic of the CV carbs and, by careful selection of venturis and jets, bogging under load might be avoidable even tho the smallest of the DCNF series has 36 mm bores and the smallest IDF has 40 mm bores. Larger sizes up to 48 mm are available. I've placed and photographed a 40IDF carb on my Venture motor w/max heads and v-boost just to see how it would fit and what kind of trouble it would be to make adapters. http://albums.photopoint.com/j/AlbumIndex?u=162186&a=7241121 I also took a shot using Venture carb mounts and no v-boost. The adapters would be very simple to fabricate in either case and even though the engine is out of a frame, it looks like there would be no clearance problems of any sort -- except the stock Weber air cleaners wouldn't clear the frame. Some sock filters or K&N individual filters could be used. I sent a version of this (off list) to a few of the more vocal and/or knowledgable list participants but they (mostly) didn't have any comments or suggestions. I probably won't pursue this further, I have too much on my plate as it is. (Tho, if someone has another 40IDF to sell for a modest price, I could be tempted.) Just thot it might be of interest to someone not wanting to lay down the big bucks for flatslides when there are low cost alternatives available.
