I have a 72 Westy with the single Weber kit and I have been trying to figure out the best set up. I have wrapped the intake pipes to try to keep some heat on them, and I have set up the heat riser to push some warm air to the carb. My mileage is about 15 around town and no better than 15 on the highway. I obviously don't know enough to mess with the jetting and am looking for suggestions for a trouble free system that I can apply without having to have an engineering degree. I see MAMW has a dual carb kit and I just do not know what would work. I live in VA and our weather is all over the place. I just did 400 miles from the Catskills in NY to home through the rain and had a lot of hesitation and stalling. I just need something that will get decent mileage and power when I need it.

Is it possible to run duel Dellorto carbs in a 71 bay that has a brake booster?
And if so where would you hook up the hose?
Thanks

I-f you can find a 4Bbl from a Mazda Rotary that has 14 Micro-Jets in it.

OR You can make a PWM to drive Your Own Injectors in tandem with the

accelerator.

Icing.......

Wrap your runners with Cu-tubing and tap the Ex-Pipes.

Dump Ex. Below engine seal. The preheating gives me 2-3 more mph

I don't think there is a prefect fuel system for a bus. Single, dual, or FI. They all have their pluses and minuses. That said, installing FI on an early T4 powered bus is really pretty easy and may be easier than either a single or dual carb install. You would need to weld on a mounting bracket for the air cleaner and come up with a return for the fuel pump. Other than that its just 4 wires to splice or add to do the install.

Done right (which takes a lot of knowledge and can be a lot of work) the progressive seems to be able to give the best gas mileage and the same or better power than other systems. It has draw backs on running during cold rainy weather.


I think the single progressive has a lot of good points and it's disadvantages are often overstated and get repeated by some who don't have a lot of experience with them. I plan on having my original dual carbs rebuilt, but the success I have had with the progressive has made this less pressing. My setup is not perfect. I sometimes get hesitation off idle, but otherwise have good performance. I haven't really done any tweaking, other than to build a linkage that works well. I have found it to be reliable. I plan on installing an AFR gauge and using this setup as a sort of carburetor 101 class for myself.

Freshly rebuilt from Tim @ Volksbitz, might be willing to sell them, have to think on it for a bit....or receive a offer I cant refuse. They worked flawlessly and will continue to recommend Tim's work!

Have manifolds and linkage as well, all factory all in very good working condition.
