Miss-Firing while Idling
« on: July 27, 2006, 15:17:58 »
Hi All - Been a while but got the Jeep through its MOT and sold it finally so it time to start my Series III 109" FFR.

It starts fine but then miss-fires and eventually stalls out.  (It had been in a field for a good few years.)

EDIT *Had alternator checked and it was fine*

So far I have tried a compression check this gave a reading of 10 on all 4 cyclinders.  The Condenser points and the plugs have all been replaced - the carb has been cleaned out - the batteries are new - a new coil looks expensive but I will give anything a go.  

All bright ideas welcomed also doesn't anyone know a good mobile landrover mechanic in the london area?

Thanks Adam

Not every problem can be solved with duct tape, and it's exactly for those situations we have WD 40

You can check the spark quality using a spare plug, if you hear a nice snap with every spark and they are blue then all is well, if it's a little weak or yellowish it isn't.  The spark should jump around 1 inch easily in normal air and still make a spark at the plug.

What grade os plugs are you using? take one out and chack the condition after it's been idling, it may be fowling up.

Are you sure the carbs are set-up properly?

Is it choking on the crank ventilation, or is a breather blocked.

How quickly does the stall occur?
