Pierburg Carb Tuning

[lukesheffield]

I have a Pierburg carb, twin barrel with electronic choke, on a 2.8 V6 cologne engine, with auto box. The van starts fine every time and runs ok when in park, but when warmed up and put into drive it stalls, so i have to keep the revs up and use even more force on the brakes!!!!!!!!!!!!!!! and its using an insane amount of fuel, but i sort of expected that, £50 in petrol Birmingham to Sheffield.

I think the mixture may be wrong or the choke not fully coming off. I'm fairly used to SU carbs and have had some experience with Weber's (34ICH, 32/36DGAV).

I will find out the exact model this evening, but could really do with some tips on how to get it working. I'm struggling to find any decent guides on the net.

I don't really want to change the carb as I ideally want to change the engine, failing that the van.

Any Ideas / advice would be great.

Thanks in advance

I had trouble before with a twin barrel carb before which sounds just the same as yours (the trouble that is. Not the Carb. Sorry!). I had to take the carb apart and clean the nozzle in the primary venturi by blowing the dirt out of it. I suspect the blockage was caused by running out of fuel a few days before which drew the crud from the bottom of the tank into the carb.

It did run right down on fuel, so will look into removing it.

Thanks
