Thanks for the suggestion, yea the oil level is good, I put 20 oz of SAE 30 in it after draining the old oil. I will check the plug the next time. I am just starting to play with small engines thanks to site like this and youtube. I needed an engine to work with so I bought this one, the guy told me it wouldn't start, never the less I have gotten it to work and have actually cut both front and back yard with it. However, after shutitng it down and having such a hard time with the recoil rope when I tried to pull it, it raised the front of the mower that's when I rotated the blade and then it worked fine, Then one time I had snap back action on the re-coil cord. I pulled the flywheel to see if the pin had sheared but it seemed fine.
