I have a 1994 50 hp evinrude. I removed the VRO system, and replaced it with a fuel pump. I emptied the straight gas out of the fuel tank, but forgot about the straight gas trapped in the fuel line and primer bulb (probably 5 or so feet of 3/8"). I ran it for roughly a half hour at idle on muffs in my driveway, occasionally revving it lightly. The fuel I added to the tank was 50:1. I'm wondering if the scenario I described would be enough to damage this motor. Both cylinders still read 150psi. Any expert input would be appreciated.
 
There is plenty of residue in crankcase to lubricate at idle. The VRO at idle was close to 100:1........go fishing
 
You will not have any problems,.----But in my opinion it is proof the oil mixed with gasoline and 2 stroke lubtication is not well understood.

Well, I'm glad it isn't much of an issue in your opinion/ experience....I'm not sure what your point is with your last comment though.
 
It has been proven many times that folks do not understand the concept of oil mixed with gasoline.----End of the story.

What am I not understanding?
If I didn't understand that gas and oil were to be mixed for 2 stroke operation, I wouldn't have even made an issue of any of this. I forgot about the gas in the tank line. As clearly stated, I mixed the gas 50:1 in the tank
 
When a 2 stroke is not running the parts are coated with oil.-----So when you put straight gas in for a minute no damage will result !!

Thanks for clarification. I do understand that as well. I just wasn't sure if the amount of gas I ran was enough to dilute/cut/wash away residual oil and do damage
