Suzuki Samurai: /stumble during acceleration..five seconds..cranking

Customer Question

What is causing Suzuki Samurai to hesitate/stumble during acceleration? Advancing the ignition timing several degrees beyond 10 degrees btdc clears up the hesitation/stumble.
Also, the motor takes about five seconds of cranking to start both hot and cold. Advancing the ignition timing several degrees beyond 10 degrees btdc clears up this symptom too.

Hello

this could be a vacuum leak after the carburettor, as any air pulled in here isn't compensated for and will lean things out

Also check that the vacuum advance mechanisim on the distributor is working correctly as if the diaphram is split then you'll be very retarded most of the time

from your description this sounds pretty likely
