I am having problems with my'83 rx-7. It has little power. It is running rich,lots of gas smell. Can the shutter valve not opening at all cause this. I need to get this fixed. Help Plz

 

hmm good question...... bump, someone help out

 

Is the car stock? if your sure its running rich, it sounds like it could be the choke sticking closed or maybe a sticking float in the carb causing it to dump excessive amounts of fuel into the motor. It could also be some sort of restriction in the exhaust as well. Post a few more details on the car so the fine people here can narrow it down.

 

My car is a stock model with al the rats nest in all it's glory and stock exhaust and carb.(niki) I cleaned out the cat but not the muffler. i will try this soon. thnx for the help. All ideas are welcomed.

 

check the vaccum system or you might have a bad carburetor
