1983 was the last year for the 185s btw .
If the head pipe isn’t leaking then you need to richen up the the jetting , if it’s back firing on deacceleration then the pilot jet needs to be bigger , stock is probably a 35 or 38 so a #40 should be a good start . Adjust the air fuel screw for the best highest idle .

Is it back firing on acceleration ?
Factory carburetor or aftermarket ?

Are you 100% sure the exhaust isn’t leaking at the head ?
