1983 rx7. Ok so I have a 12a with a nest delete and a stripped nikki. The car will run but sounds ported and like it has a misfire. This is not the case. What's happening is my rear rotor everything is fine rear ventrili is fine works great BUT my front is getting spark, getting air but not fuel and causing a "misfire" my front ventrili is just dripping slowly while my rear is working away. But my jets are clean and and all my passages and my bowls are set right. When you give the car has both ventrili go to work and work fine just the front is a little less than the rear..... The carb has been rebuilt and cleaned numerous times. This is the last thing I need to put this car on the road. I pulled it out of a field were it sat for 15 years. And put it all together from nothing it was just a shell. Please tell me someone has ideas

 

welcome to the board.

i am tempted to say it's a needle/seat issue with the front, but honestly, i am not Nikki-savvy enough to say that with confidence, so i will see if misterstyx69 will move this to the Gen I forum.

for future questions like this, it's probably best if you post them in the Gen I forum or New Member Tech.

good luck.
