This came in from my brother-in-law as running before a big puff of white smoke and then no start. He reported the same problem from last week.
Ignition check was good with good spark.
Compression check: I put my thumb over the spark plug hole and asked by brother-in-law to pull her over for a preliminary compression check... a 4 foot long firey flame of hell came blowing out of the cylinder igniting the machine and my entire right arm. I ran around the garage beating my arm against my leg trying to put out the flames, eventually, pulling my sweatshirt off to save my own life. I learned something today...and got a good laugh at the same time. The machine was obviously flooded and once the fuel burned off me, I was good as new...just a burning on my hand every 15 minutes, which was alleviated by some cold water. I'm thinking 1st degree as I have no blistering or peeling.
So I obviously had fuel delivery.
Checked the oil and it was way overfilled. Maybe 8-10 oz extra. I drained it to its optimal level. The air filter was soaked with oil. Once I pulled the air filter, it started right up. As soon as I installed the air filter, it would stall immediately. Problem solved.
My question is, aside from draining the excess oil out and replacing the air filter, is there anything else I should be concerned about regarding the machine running for a certain amount of time with too much oil?
