Question 2500 rpm problem

Hi there i´m a newbie to the rotary world.

A few days ago i bought a 86 N.A. FC, the car is a little
rough but all in all an okay car. My problem is that at around 2500-3000 rpm(in neutral) the engine has got this hesitation allmost like it´s getting too much fuel, plus that it has used 3o liters of fuel in only 120 km.

What could cause theese problems and how do i solve them I am kinda lost here so please help me.

Are you sure it's 2500-3000. There is a known problem at 3800 (do a search, you'll find a millions posts ).

You should do the regular maintenance things... change oil, spark plugs, filters... that sort of thing. You never know what the previous owner did.
