| Hiya,
I would suggest getting the OMC motor tuner treatment. on your particular motor, there should be capped end that is threaded like a bicycle tire's air inlet. if you purchase the OMC treatment, it will screw directly to that, and you inject it directly in as a treatment to the whole combustion chamber, carb jets, etc. Really does a great job.
Then, when you are done taking the motor out for a spin to clean all the gunk out and burn all the white smoke you create from the cleaning, replace your spark plugs.
If at this time the motor is still not running well, grab a timing light, and check the timing. On that motor, at warm idle (800 rpm), it should be at 0 TDC on the upper piston. If it is not, adjust it. Pretty simple to do...just follow the linkage to one of the screw on ball-joint ends. Unhook, make a turn in the correct direction (base this upon which way the timing needs to go), rehook and check timing. If you get it to 0, it should purr like a kitten.
It may be just a little carb tuning as well....
Easy motor to work on...had one for 5 years or so before I upgraded. Loved that motor.
