i have a 1983 rx7 12a. i drove it home from where i got it and it was not pretty. For starters it needed to be reved up to about 3k to let clutch out with out killing it. I replaced the plugs, plug wires, fuel filter. I cleaned the carb and am lost now.

 

Man i'm having the same problem with my 85' 12a with no luck. if you figure anything out please let me know.

 

what have you all tried to fix it?
I am going to look into the timing

 

Check in the FAQ in the first gen section. Could be a vac leak, or even a bad engine. Pull the spark plugs, crank over by hand and see if there is a noticable difference in the pulses. They should be even, and cosistent.
