hey guys its denton here, with the 83 fb. im getting horrible mpg right now. i put 15 gallons in a couple days ago and drove 102 miles on it and it ran out of gas this morning on my way to work. (wich i was late) i didnt even think to check the gas gage cause i just filled her up. i have a webber 48ida on it right now. and i need to get bigger jets and chockes for it. could that be why im getting awful gas millage? any help would be great. thanks!

 

yes - check your oil, I bet it's diluted with gas. Fix the carb and change oil.

 

well my omp pump is disconnected so i pre-mix the gas right now. would it still be in my oil? rotor shaft case ?

 

Nothing to do with the OMP. Pull your dipstick out and smell or drain the oil from the pan. If your going through that much gas, not all of it is getting combusted.

 

check for fuel leaks i had a leak on the back side of my fuel return line and you couldn't see the leak i felt it when i put my hand behind it and once you fix this problem you will still have bad mpg because brap

 

Just be carefull, i have heard stories of rx7s catching fire from fuel leaks in gas hoses...

 

thanks guys! where would you suggest for me to check for fuel leaks?

 

Check the tank, fuels lines, fuel pump, fuel rail, etc. Basically anything that has fuel flowing through it.
