Well I've been daily driving the BIS for 12 days now, and it's had no problems 9 out of 12 of those.
Sometimes after being parked for a few hours, it won't start. Each time I've got it going again by setting the static timing with a test bulb. It's never the first time either:
I set the timing, turn the key,
set the timing, turn the key,
set the timing, turn the key and
THEN it'll go.
I just don't understand it.
And now today it's refusing completely, I either hear a loud BANG once I stop cranking or conversely a gentle "poot" backfire.
Once it's going, it's fine.... and when I check the timing with a strobe light it's jumping around the 10* mark too.
I'm convinced BIS must stand for Bloody Ignition System.
