  • Great Value and great performance

    This carb has been fitted to my 1982 2000 air cooled T25 as the old solex carbs were well and trully kaput !
    Great carb with increased performance making over taking easier.
    Note the carb slipped along the inlet manifolds and i have since fitted jubilee clips on the carb and manifold end of the rubber pipes and now it a reall bad boy

  • Great value for money!

    I bought this little bad *** for my 2.0 1980 T25 and I'm chuffed to bits with it! It takes a while to fit and you have to reposition the throttle cable but it makes a massive improvement if your old solex's are knackard! The instuctions aren't the best (They are quite vauge and writen for the US market as they refer to the right side of the van as the passenger side) but any top bloke with DIY experiance will be able to put it together! I'd recomend buying half a meter of 7mm fuel hose as the one provided in the EMPI box is too short. Also if you get the smaller air filter it comes with a free Scat sticker! If you've got carbatooter problems this is the best value for money kit around!

  • What a difference

    This super carb conversion was fitted to my 1972 bay which has a T4 engine. The worn out twin carbs have been bined and replaced with this carb. Even without setting up on a rolling road, I have now got better MPG and much better performance. Highly recommended

    • I have a CJ, is this a straight repacement for the exisiting set up?
    • Answer: This is a straight replacement on a cu or CJ engine but may need drilling and tapping for a vacuum take off for a vacuum standard distributor. The T25 vans will need modification to the engione lid or a low profile air filter.

    • Do I have to tune this or is it basically set up straight from the Box?
    • Answer: All carbs will need fine tuning to gain optimum efficiency, ideally with a session on a rolling road to get it spot on. but they are set up to get you running from the box

    • There is a brass tube on the side of the unit, just visible under the air filter in your photo, what is this the take off for? and where do I plumb the fuel tank vent pipe or do I tap into the air filter plate?
    • Answer: I'm sorry I can't see the pipe you are refering to. The fuel tank breather will need to be tapped into the base plate.

    • I have this unit fitted to a 2.0l aircooled engine, but it tends to suffer from carb icing in cold weather, do you know how I can reduce / stop this?
    • Answer: The manifolds can ice up on occasion on any carb, normally this is an indication of the mixture not being quite correct

    • I have fitted a single carb conversion kit supplied by yourselves ,theT25 now starts ok but when warm has a very bad flat spot on pick up from tickover,any idears.
    • Answer: I would suggest setting the carb and timing up with the vehicle on a rolling road as the carb comes set up for an average engine, just to get you up and running but to get peak performance you will need to tune the carb for your sepecific application
