Yes 2-strokes smoke but,
What kind of motor do you have?
Oil injection? Have it checked.
If not, what is your Mixture? maybe your useing too much.
Try Penzoil 100% synthetic, it will smoke more on start up, but burns alot cleaner when underway and is much better for the lake & fishys! So I would think it would be easier to breath all the way around!
****If you switch, make sure you empty all the oil out of your tank and change your fuel filter or water seperator (if you have one)! Synthitic and oil don't mix, it makes gum!
My two cents!
