When I changed the oil on my edger this spring, I accidently overfilled the crank case. It is a 3.5 HP Briggs vert shaft.
When I started it, it smoked heavily. It ran for less than a minute that way. I discovered what I had done and corrected the oil level. Now, when it starts, it smokes heavily for about 15 seconds. It still starts real easily and runs fine. It doesn't smoke after the initial startup. What do you think I have done? It is time for oversized rings? If so, why does it only smoke when it starts? The motor itself is 5 years old.
