Sorry about a question about MGBs but I know there are some people out there
with multiple LBC interests so thought I would try.
QUESTION:
Just installed a new K&N filter on a 78 MGB in place of the original
equipment Zenith carburetor (no pollution control equipment or other
complications). Car runs well on the driveway or during acceleration but
once up to cruising speed the motor falters and sounds as if it is going to
stall out. When I pull the choke out it helps and the motor sounds almost
normal.
Would the K&N change the needle setting and is there a need to readjust.
Thought I should ask before I fiddle with the carb never adjusted a Zenith
carb before, always had SUs .
Thank you, glenn
