Just picked up a Yard Machine for cheap, owners said engine was locked and wouln't start. Got it home, took my breaker bar and found out that the deck drive pulley didn't disengage and was putting too much strain on the engine, so wouldn't turn over. Got it to turn over, made sure I was getting gas, has good compression, getting a nice strong spark, but all I am getting is white smoke out of my intake. I took off the oil cap and white smoke came out of there too, and after checking the oil it was milky. I am guessing they left it out without anything over the intake (no air filter) and it probably got water logged, but I do not know where to go from here.... It is nighttime, so I was able to see that there was a flash of light, like it backfired maybe, out of the intake.
Where do I go from here?? This has everything that I thought an engine needed to run. so why is mine not firing?
Trying to get this running for my brother's wife's grandma, because theirs crapped out, so any help would be greatly appreciated!!!!
