Low engine power on cold mornings....

[redking13]

Hi All,
Very new to all this, but here goes!! Recently purchased VW T25 Hightop Automatic 1900cc (VW Virgin!!). With all of this cold weather we have been having the bus really stuggles to move once fired up (and I mean really struggles) any suggestions would be very much appreciated.
Cheers redking13

Here's the starting proceedure for a 1.9DG engine with an automatic choked Pierburg carb. ... this is the most common set-up.

When wanting to start from cold ....

With keys in left hand (and after checking oil and coolant levels) press the accelerator pedal to the floor and gently lift off your foot.

Insert ignition key and start engine without touching the pedal.

Engine will fire and rev up to ~2000 rpm

1 gentle blip of the pedal will knock it down onto '1/2 choke' ~1200 rpm

leaving the engine to warm this should knock itself off when warm onto normal tick-over which is ~800rpm otherwise another blip of the pedal will probably do the same.

This on a manual DG or DJ running a Pierburg carb.

Hope this helps. Ian.
