stick it in the fridge and use it as a jelly mould hence the fridge temp should keep it working properly icon_biggrin.gif icon_biggrin.gif icon_cool.gif

Difficult without seeing it - a service might help, otherwise check cooling system, choke system, waxstat air intake temp system, main jets, ignition timing,crankcase breather, etc... for starters. Is the guage reading hot when prob. occurs? Check fan belt for correct tension, radiator for clear fins, thermostat. Sorry to go on, but this could be anything.

I would check the mixture it sounds to weak. I suspect in cold weather the choke may be on a bit which will richen the mixture, the car would then seem OK. As you say in summer this wouldn't happen. You need to check choke operation and the mixture, as a starting point.
