I have a wizard WG4, was told i need a 16 to 1 ratio of gas to oil....i mixed 1 bottle of oil to 2 gals. of gas and the motor smokes like crazy...when i bought it and ran it with what was already in tank no smoke hardly at all, i have never owned a gas motor. I'm wondering if the previous owner had straight gas just to start it up for my demo. or am i doing something wrong...Oh, by the way, the oil was 16oz. that i mixed with the 2 gals....NEED HELP
Your mixture is correct for 16:1 -- 16oz. of oil for 2 gallons of gas. Especially when you are just running it in a bucket, and just after start-up, they tend to be really smokey at that mixture. It could also be running a little but rich, but to properly adjust the carburetor, it needs to be on a boat under load. Now, if you can't see your hand in front of your face, you might have a problem, but don't be scared of a little smoke...that's what these oldies do.
A synthetic blend or full synthetic TCW-3 two-stroke marine oil will help cut down on smoke a little bit. But, once you get them out on the water and get the carb set, you probably won't notice the smoke that much even with regular TCW-3. Also, make sure it is pumping water well to ensure the powerhead is being properly cooled. Replacing the impeller if you don't know its age is good preventative maintenance.
