Sidedraught Carbs & Brake Servo

[Guest Twoscoops]

Can someone answer me what is probably seen as a really stupid question.....

 

If you fit DCOE/DHLA carbs on a pinto for example, what do you do with the pipe that normally goes from the brake servo to the inlet manifold..???

[Guest Bazwaz]

Some manifolds come a vacumn take off already drilled. On the others there is usually a place where you can drill and tap your own hole to take the vacumn pipe.

My servo is not plumbed in,I found the brakes were too prone to locking up.

There was a tapping for servo take-off from number three intake and a feed for the heater pipe from the cylinder head water jacket on the manifold I bought. You must have this for water circulation before the thermostat opens. The manifold should have provision for both.

I've got a feed for the water in the manifold and there is a bolt in the top of number four inlet but when I take the bolt out it just goes into the casting...???

Compare the thread on the 'blanking' bolt to the thread on the end of the servo pipe nut. Bet they're the same and you just drill a 4mm hole through into the intake if you want to run a servo.

If i do that won't it draw up fuel from number four intake...????

[Guest Bazwaz]

No. The vacumn is created by pulling air/fuel mix into the cylinderand pulls the air from the servo in the same direction thus creating a vacumn in the servo.

Theres also (there should be!) a non return valve in the pipe.....
