Help my clipper cab has a weber with a water pipe going to the side of it. my question is about the heater element in manifold. the wire was never connected when i bought it. so today for the 1st time car is stalling...restarts after 5 mins. presume carb icing, also temp gauge nevers go's above a quarter. heater works ok though. does the weber still need the maniflod heater?
A weber dtml (the usual weber replacement for golf) does still need the manifold heater connected. However, if your carb has a water connection it doesn't sound like it is a dtml (the manifold should have a water connection with a dtml though)
Mine is big thick red/white wire...left it disconnected on mk1 as was summer when i bought it. only seems to stall when you go about 70-80 ish then it stutters
The 'hedgehog' heater would only be on for the first 4 or 5 minutes after a cold start anyway, so if your troubles continue after this time, having it re-connected ain't gonna help.
The carb models have two heaters, the Hedgehog manifold preheater controlled via the thermostat, and carb preheater, which is at the bottom of the carb facing the Camcover (on a webber) you can just see it on the picture. Make sure both of these are working and also the flap in the airbox is working, and your mounting gasket is A1 condition.
It's essential that the warm air duct is present between the airbox and the shield on the exhaust manifold. I had to fit this to two of our prevous MK2s (all with Weber carburettors) to cure carburettor icing.
