H32/34 PDSI carb Fron CB Performance

[Herrbern]

Hi,

I have bought the sp dual H32/34 PDSI carb setup from CB Performance that I have installed on my 1500 68 bug and I was just wondering how the trottle return springs fit. I have no idea where they fix.
Don't hesitate to post a picture if you have the same kit.

Thanks for your help,

Bernard

This help ya?

My springs are attached to homemade tabs on the rear head tin screws.
Good Luck.

I have a 019 on the car. I haven't adjusted anything yet, so I will see how the dizzy works with these carbs.
Thanks for the tip.
Access to the adjustment scews are not easy compared to kadrons. But I will make it.

Thinking about getting these carbs for myself... How do you like them so far? Out of the box were there any apparent issues? How is the overall quality? They seem like good value for those of us who don't care for blistering performance but would like ease of starts without the issues of a centermount.

Herrbern,
If you look closely at the pic I posted above. You can see a small washer soldered in the volume control screw slots. This makes adjustments a little easier since there is no room to get a screw driver along side the carbs. I use a coin to adjust the idle when needed.
Good Luck.

Good to hear! I see you're running the stock pump and a fuel pressure regulator too... similar to what I am thinking too. Nice to hear they are working out, I was thinking for smaller displacement motors this would be great. (Mine is a 1700 dual port... I do have to re vent and jet them but I'm not worried about that as much as I am about float levels etc..)

The soldered washer idea is BRILLIANT!

The washer idea is great. I will do it this weekend. Thanks

Hang on a bit. I'll post a couple pics of the filter and washer setup's. It's early here.
Have a great day.

Ok here is the washer soldered(tin) into the screw groove

This is the barbed fitting that I installed into the right filter base for ventilation.

And this is the bowl vent setup. It's a short length of exhaust pipe with a nipple welded to it.

I hope all this helps.

Thank you for the pictures.

Hi 67rustavenger,

I can not have those carbs work properly. When I adjust the idle with the carbs sync, when accelerating, the engine seems to turn on 3 cylinders. It's like it is getting too much fuel. Spark plugs are black.

What is the jetting for a 1600cc engine? Is it the jetting from CB Performance ok, or do I have to rejet the carbs ? And what about the accelerator pump quantity?
Finally, the springs seems to be too fexible to recall the levers to the idle screws. Are you using them on your car, or have you replaced them ?

Thanks again for your help

they are jetted for ethanol out of the box, which is why you have black plugs.

Do you still have the puny 22mm venturis? Step up to 28mm.

You are right. My venturi is 22mm, with main jet 130 and air 100. The engine is running too rich.

I will change the venturies on both carbs.

[Herrbern]

I have received my new venturies and will reinstall the carbs in the coming weeks on the car.
I still have some doubs about the quality of the central linkage.
Which other linkage can I buy? Scat or csp even if they don't mention the pdsi carbs....
