1hz exhaust smoke
How can stop my 80 series cruiser with 1hz to stop blowing soo much black smoke??

Re: 1hz exhaust smoke
Check the easy things first,
Air filter
Intake restriction
Exhaust restriction
Then look at the fuel screw on the inj pump (faces towards the firewall just above the fuel shutoff solenoid). It may have come loose.
Older engines get what is called governor growth, where the stoppers wear out and allow more throttle and fuel metering.
If everything looks ok, wind the fuel screw out a few degrees and try that. Too much smoke still? Try turning the screw more. If you are having to turn it more than 1/4 a turn back there is something wrong.
