Base plate before carburetor

[willhill92]

My mechanic says I should replace the plastic base plate before the carburetor and also my accelerator pump isnt working.. just got it back from him and it drove like shit... im just gonna throw on my old carb any ideas where to get a new base plate from before i do this?

That the one between the manifold and the carb? It have an electrical connection?

 

Just swap the accelerator pump.

[willhill92]

yes the one with electrical connection and where is the accelerator pump located?

The pump is right on top of the carb.  You can actually take it apart to clean it without removing the carb.  (had to do this once)

It's the little plunger on the front right when standing at the passenger side fender and looking at the carb.

 

You may need a magnet tool to get the little check ball out so you can shoot carb cleaner through the pump.  Don't forget to replace it and put the

spring back in correctly.  You can also get a new pump plunger without buying a whole kit if the plunger is torn.

 

The mechanic couldn't do this????  It takes all of 15 minutes.....

 

The spacer plate is actually a fuel mixture heater for winter time.  Also acts as a spacer and insulator.  You should have it, even if the heater

isn't used.

Unless that heater is leaking vacuum you don't need to replace it. It warms intake air to help evaporate the rich fuel mixture on start up to reduce hydrocarbon emissions when the motor is cold.... any time of year.

they said it has a bad vacuum leak

[datzenmike]

Well then replace it.

thats what i was asking, where can i get one too replace it? 

[datzenmike]

Any auto supply house should have one, auto wreckers, #16174-80W00 from Nissan but almost $100. Or make one out of a piece of thick fiber glass.

I literally cant find a  fuel mixture heater.. tryed my local nissan dealership.. searched online and at several local auto parts warehouses.. im thinking i might have to fab one myself.

[datzenmike]

Try auto wreckers. Hell it doesn't even have to work just seal between the carb base and the manifold.
