I have a problem with my nissan sentra 1990. I removed the starter motor to replace the carbon brush but when removing I also removed the sparkplug so when I put every thing back I tried to start the engine but it became hard starting and then I removed the air intake or air filter I dont which one is the right term the thing connected above the carburetor then it started but it was backfiring verry loud and verry strong uneficient fuel consumption. Pls help I dont know if I need to do something with the carburetor or just replace the air filter. Thank you

Sounds as if you have an ignition lead to a spark plug on the wrong plug, re check these first.

I already tried it sr. If the sparkplug is plugged in the wrong plug it wont start. I really dont know what to do but I know that the sparkplug has nothing with the backfire. I think theres something clogged in the carburetor or not enough fuel flowing to the carburetor. Thank you very much sr.
