alright well two things that I need to ask about.. first is my fuel gauge which doesn't move from empty. Previous owner said it was a ground wire problem? But I'm not sure exactly what the problem could be, does anyone else?

Another thing involves white smoke. I get the normal smoke at cold starts and everything but when the engine is at normal temperature, driving, and is redlined, a small cloud of smoke can sometimes be seen. is that normal?

Verry new to rotarys and rx7s, by the way

 

The smoke should have a slight blue-ish tint. That is because the oil metering pump mixes a bit of oil in with your fuel when you open the throttle wide.

 

Yeah now that I think about it seems to be a little blue, and it's not really a lot of smoke you can just kinda see it
