<DIV>Loosen the linkage between the carbs so they work indepently. The slow the
idle speed down on the front carb and bring the rear one up until they are
equal. </DIV>
<DIV>If that will not fix it then if you removed the throttle plates they were
not set correctly and you will need to remove the carbs to re set the throttle
plate with the idle screw backed off. Make sure the the plates are sealing off
completely. If not loosen the shaft screws and move the plate until they almost
completely seal all the way around.</DIV>

<DIV dir=ltr>Hi everyone,
<DIV> </DIV>
<DIV>I am at the point where I'm trying to tune my carburetters for my
BJ7. The engine was rebuilt along with the carbs. I set up the carbs as
per the SU workshop manual to pre-tuning setting: throttle screw backed off,
turned jet adjusting nut/screw down two turns and turn the fast-idle adjusting
screw until they are well clear of the cam. </DIV>
<DIV> </DIV>
<DIV>The car starts well enough without choke engaged, but the engine idles at
2000 RPM even after left running for 5-10 minutes. The rear carb doesn't seem to
have any suction unlike the front carb (I put my hand in front of the carb for
this test). Any ideas why the rear carb does not have any noticeable suction? I
suspect the high idle is due to rear carb not functioning properly.</DIV>
<DIV> </DIV>
<DIV>Any help would be appreciated.</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>
<DIV>Mike</DIV>
<DIV>'63 BJ7</DIV></DIV>
