wardy18 33 1 Cars Posted July 27, 2009 There must be a fair few Webber experts out there by now, i have a very puzzling question to me which someone might be able to answer straight away!! I have one of those Carb Balancer guages that you stick in each trumpet to get a reading, now say starting from the left (cambelt end) on the carbs, i can balance intakes 1, 3 and 4 at the trumpet with the guage but i just cant seem to get intake 2 to read as high as the rest, ie if i get the rest to read say 8 on my guage this one will only read 6.5 - 7, this will be the case no matter how much i adjust the mixture screw can anyone tell me what might be goin wrong!?? obviously something must be wrong inside the jettings etc for intake 2 also to adjust without the gauge do u adjust each mixture screw until the revs dont raise anymore then knock them back 1/4 turn!? I really hope someone can help with this (oh and i cant get it to a rolling road as we dont have one on the island) Share this post Link to post Share on other sites
mbayley77 0 Posted July 30, 2009 Balancing carbs is done via the connecting adjuster screw bewteen the two sets of carbs - i guess that all four should then read the same??? If you have a single cylinder reading low could it be that that cylinder has a leak either in a carb seal or a head to carb gasket? I had this and everything seemed fine accept i couldt get it to run just so. Turned out to be the gasket leaking. Take it off, clean and re-seat, completely different story. As for you setting of the mixture screws this principle should be fine to get a basic level of drivability - i got what i thought was great, and then had it tuned on the rollers and was amazed at the difference.

wardy18 33 1 Cars Posted July 30, 2009 ah ok ill remove the carbs and re seat and then get all mixture settings set exactly the same to start off at one point then ill balance the 2 carbs via the connection rod adjuster then see what the gauge reads on each cylinder and go from there Share this post Link to post Share on other sites

wardy18 33 1 Cars Posted July 30, 2009 Could also be a twisted spindle. causing one butterfly to be open more than the other........ very possible!! ill open both inspection screw nuts and check the butterfly positions to each other Share this post Link to post Share on other sites
