I've got a rather annoying problem once the B has been driven at freeway speeds or high rpm through the gears the idle becomes erratic and will die if the gas is not goosed once or twice when coming to a stop particularly a hard stop. If I push in the clutch and hold if for a few seconds she will also die. Stop and go traffic is getting very hard to drive in.
Symptoms
Stalls while stopping clutch out car in neutral. If it does not stall idle will drop to 500 or so and then recover.
Stalls when clutch is engaged. Crankshaft does not appear to be moving with the application of the clutch. Previously would drop 200 rpm with the clutch engaged. Did the pre rebuild and post rebuild.
RPM via the Tach will read 12 to 1300 when idle is set to 900 via timing light. Also the tach is rather erratic bouncing 1 to 200 rpm.
Occasional pop through the carb. Generally will kill the engine when it happens.
Stumbles when trying to keep the engine alive.
Settings
Idle at 850 to 900
Timing 15deg at 800
Weber 38 outlaw low end needles a hair under 1 turn out.
New 45d4 euro spec with new Lucas sport coil and wires.
Idle mixture seems to be good. Car transitions clean from a normal idle. Gunson was reading 3.8 at idle
Plugs look great
Runs fantastic otherwise.
Runs cold but I am about to change to a 180 degree t-stat when the car cools off.
Getting ready to readjust the valves
Any ideas on an attack plan?
