Acceleration Problem

Featured Replies

I have had my brat for a while now and it has always hesitated when stepping on the gas. I have lived with it now for a year, but now it is getting annoying. I have a 83 GL 4X4 auto :boohoo: Brat. And the hestitation will not go away. Even after the car warms up it still want to stall whenever I take off.

 

I have lots my subaru manual and really don't know where to start. I have a weber carb, but have been kind of hestitant to put it on. But that may just be what I need to do.

 

Any help would be great or even just a starting point.

 

Thanks

Vo:headbang:

does it cut out momentarily as soon as you hit the gas? it could be the accelerator pump on the carb, seal dryrotted or the like. what it does is sqiurt a shot of gas into the carb until airflow can get the rest of the fuel moving(the atomization effect, burnoulli's principle)

 

if its not working, you get a shot of just air, thus the motor wanting to stall, right before the fuel starts to flow and get it going.

 

how is general driveablility other than that?

That is exactly what happens. This is the only problem I have, the brat drives fine after that. when it is cold it is hard to get moving almost vibrates or sputters.

 

Anything else Fox please let me know

if you liik at the top of the carb, you will see a little lever that pushes down on a "plunger"

i think it can be replaced without removing the carb. you will have to take the top of the carb off, but that doesnt risk any sealing or risk creating vacuum leaks.

 

check the parts counter for "accelerator pump" and see what they give you. shouldnt be too hard to do.

 

i had the top of a carb off and back on, no new gasket, no silicone, no problem.

 

just be careful not to booger the screws, some of the can be tricky
