JMAYHALL Posted October 21, 2020 Report Share Posted October 21, 2020 I have a 1976 B210 and would like to swap the carb to a Weber 38. Does anyone know which adapter I will need to install the new carburetor? Thanks, Jeff Quote Link to comment

Does anyone know which adapter I will need to install the new carburetor? Thanks, Jeff Way too big a carburetor. The 38 is for six cylinder and small V8s. Even a 32/36 is too large but if you don't mind the trouble to 'drive it' it will work. Better to have a carb that is small and wish it were larger than a carb that is too big and wish it were smaller. Quote Link to comment
JMAYHALL Posted October 22, 2020 Author Report Share Posted October 22, 2020 I should have asked "which carburetor should I get" first, lol. I'll give it a shot. Thank you both for your help. Jeff Quote Link to comment
datzenmike Posted October 22, 2020 Report Share Posted October 22, 2020 Now if you plan a GX head and a LARGE cam with headers or perhaps a blow through turbo a 38... maybe. If you want something that is easy to drive all year round in all weather and driving conditions I wouldn't go above a 32/36. Now this is just an opinion, and you will always get someone who has done this that will say it worked perfectly, but I warn you you will have to compromise and put up with things you may not want to.

difrangia Posted October 22, 2020 Report Share Posted October 22, 2020 Consult Pierce Manifolds for recommendations on jetting the 32/36 down for the smaller A-Series engine. they could probably supply the adapter and carb jetted down for your application. I have a 32/36 jetted down on our 1200cc E1 engine and have never had a problem with it. Gonna put one on the 620 next. Both of my 32/36's have 'Made In Spain' cast into the body. Beware of Far East knock-offs. https://www.piercemanifolds.com/https_www_piercemanifolds_com_category_s_99_htm_s/99.htm Quote Link to comment
datzenmike Posted October 22, 2020 Report Share Posted October 22, 2020 It would seem to me that a carburetor doesn't know what displacement engine it is on. It simply mixes fuel with the air going through it based on how much air volume. If you have an L16 and the carburetor's jets are selected to get a perfect 14.7 to 1 a/f ratio then this carburetor will still give a 14.7 to 1 a/f ratio on a smaller A14. The A14 at any throttle position is simply drawing 14% less air volume... like an L16 throttled back and pulling less air. At 3,000 rpms an L16 uses 2400 liters of air. An A14 at 3,428 rpms uses 2400 liters of air. So my question is how or why would a carburetor know or care what engine is drawing 2400 liters of air through it???? 1 Quote Link to comment
