My brand new 2016 Viking would almost always take 2 tries to start when cold and I also had gas in the crankcase. Turned out to be a loose spark plug wire at the plug. Firmly seated the boot and ran much better. I may add I was not getting a red hot exhaust like everyone else until I fixed the loose spark plug boot.
I think this answer went unnoticed many years ago. Massive may be onto something, as failed starts continually push fuel. Somebody with more knowledge than me, let us know if you think that failed spark/starts can push too much fuel (fuel injection), whereby it mixes with oil.
Yep. I had a very old spark plug. Changed it and the oil Crossing fingers that was the cause. Went a year with failed starts. Cranking right up at first turn of key now.
