Hello everybody, I have a 3.5hp Johnson 2006 model and even when it was new the smoke geting out of the foot was too much about the double or triple of the usual 2T outboard smoke. I tried the 1:100 mixture and even less but nothing changed. I communicated with an authorised service and they told me that this is due to that i don't use the Johnsons' special oil . Can anybody help me ? Thanks in advance.

??----The motor needs oil to live !----Why would you try running with less oil ?-----Just another example of folks not understanding the concept of 2 strokes and lubrication.----What trouble shooting has been done ?

This is what i meen too much smoke...the colour i think is grey which means it's oil . I don't know if the black colour in the bucket indicates something. What i noticed and it's also in the video, when motor runs out of fuel, momentarily the rpm goes higher. I don't know if it's normal or indicates rich fuel. I m going to post the spark plugs' picture in a while

Need a bigger bucket to test run that motor.----Water must be 6" ( 15 cm ) above the impeller.

Here is the spark plug look, it looks shiny from oil and i think it smells oil, a little blacky, and rusted (i think it's normal for a 17years old spark plug)
