Carb freezing

<< < (3/3)

TBM:
Is your fan coming on too early?

Most of the Weber carb icing problems are also caused by the standard fan blowing cold air over the carb.

I ran a Weber with a K&N in the Welsh Mountains for four years and never had a problem -most have attributed this to the kenlowe. However I didn't have a heat shield fitted. I also had a higher temp thermostat as well.

Are you sure it's carb icing and not a fuel problem?

Does your bonnet seal well? I fitted some sticky neoprene tape along the wings where the bonnet sits which also kept it nice and warm.

Is this series driven much? as water in the fuel from condensation can cause freezing, and if oil bath filter a clean and oil to right line may help.
Ah the joys of petrols!

Dave123:
Yeah, the series was sat for a while but about a month ago I've driven it everyday. I'm pretty sure it is Carb freezing because it showing all the symptoms. It's fine when idling cold or hot, it's fine when running cold or hot but it's the bit between being cold and hot when moving seems to be where the engine just won't Idle. You have to idle it with your foot.

In this week though it seems to have developed a problem where it misfires badly enough not to idle when I'm warming it up. When it is warm though you turn off the key, restart and it's fine. I'm just wondering if it's connected?

My tutor advised me to buy new plugs and leads anyway which i can get cheap-ish through the college it's also a 'Job-Card' I have to complete. So I'll be getting new everything including dizzy arm and rotor cap and coil and hope it fixes the misfire then see if it will Idle when sat still or when stopped when cold-warm moving

NiteMare:
the idle problem when cold can be caused by a mixture of dirt/dust/perishing and damp on the high tension side of your ignition system ...

again an old volvo had this problem first thing in the morning (i lived next to a stream), i used to stick a fan heater under the bonnet for 5 minutes to dry everything out before starting for the first time of the day, once the damp was gone it'd run just fine
