1)  The smallest diameter you can use is 0.800 mm. There is no danger for the engine but the car will have slow acceleration.

 

2) Air jet = 1.30 mm. Fuel jet = 0.45 mm.

 

3) There are two type of gaskets:

• old type made of steel covered with rubber (see photo 1)
• new type - sandwich type - a steel plate, a bakelite spacer, and 3 cardboard gaskets (see photo 2)

Hi aclaim3

 

Your message is not too clear. Write in Spanish then in English like I did here. Try to be very specific.

Hi Ricardo:

 

How to change the carburetor gasket? (Rubber coated steel joint)

 

Is it necessary to put some sealant on the underside of the gasket that goes to the engine?

 

Between the carburetor and the gasket is there any gasket?

 

Thanks for your help and understanding

Hola Ricardo:

 

Cómo se debe hacer el cambio de la junta del carburador? (junta de acero cubierto de goma)

 

Es necesario poner algun sellante en la parte baja de la junta que va al motor?

 

Entre el carburador y la junta va algún empaque?

 

Gracias por tu ayuda y comprension

How to change the carburetor gasket

This is a basic guide. It doesn't describe how to remove every nut and bolt. Use your common sense.

1. Remove the cover of the air filter housing (4 screws, 6 clamps)
2. Remove the air filter
3. Unscrew only 3 screws (#1 in photo 1).
4. Remove bracket 3 (photo 1)
5. Remove the bottom part of the air filter housing and the air duct (you'll have to remove one more nut and two hoses)
6. Remove the accelerator cable (photo 2)
7. Disconnect all electrical connectors and fuel lines to carburetor.
8. Unscrew 3 long screws (#2 in photo 1). The carburetor should remain attached only by the coolant hoses.
9. Unscrew 4 screws that hold the bottom carburetor gasket.

The installation is performed in reverse order.

 

Important notes:

• The new gasket must seal perfectly. Any vacuum leak will cause major problems. Unfortunately the carburetor gaskets sold today are made of low quality rubber (China) and they are not perfectly flat. That is why I recommend using fuel-resistant silicone applied on both sides of each surface. Let the silicone cure for 20-30 minutes before assembly.
• Do not torque excessively the 4 screws that hold the gasket. That is a common mistake. The manual says 8 Nm.
• The same thing applies for the 3 long screws that hold the carburetor on top of the gasket.
• It is possible that perfect vacuum is achieved after driving 15-20 km with the engine warmed up.

You need calibrated pins.
