RX7CATALYTIC CONVERTER OVERHEATS

1985 Mazda RX7

We got a 1985 mazda Rx-7 with Rotary Engine with 135000 miles on it. Engine runs but spews out bluish smoke from catalytic converter, (which also overheats), and acceleration is terrrible, when the pedal is floored it has no noticable effect on the speed.

Also if you could help with this--
I recently took the enitre carburetor off and cleaned it, however I forgot how the hoses were positioned, I didnt mark them well enough. Unfortunetly, I cant find a clear schematic for the vacuum hoses. I have copies of allhte manuals ever created but they dont make a clear enough picture. So I might have some vacuum tubes connected improperly, but I am unable to fully verify this.

Sounds like you might need a new catalytic converter
