I have a 89 merc classic 40hp--oil injected 4 cylinder and it smokes alot.I think it is more than it should,i leave a blue haze behind me,,and when the wind is bad u inhale the blue smoke.Im wondering if i can adjust the mixture.....thxs
Had the same problem with mine. I started using Arctic Cat APV synthetic injection oil (same stuff I run in my sleds) for 3 years before I sold it. Helps with the smoking ALOT, the motor also started better. Drawback: its VERY expensive $$$. You may get the same results with the Pennzoil synthetic ?? and its quite a bit cheaper than the A/C oil.
best adjustment you can make is to scrap the autoblend unit and mix the gas yourself - it will fail without warning and then your motor is toast . i got rid of mine the moment i purchased my 88 classic fifty .
