porter cable generator start problem

[maidens54]

Problem starting Porter Cable 5250, BSI525-W, Type 2
Switched spark plug, used starting fluid, acts like it wants to start and then just shuts down. Thinking of changing oil since that is the only thing left I can think of. Oil level sensor may be causing a problem?? Oil level appeared normal prior to starting but now the oil has taken on a liquidy muddy appearance.
Anyone have this problem with this generator before?

Magneto flywheel surfaces probably need cleaning. Emory cloth works best.Clean until surface is bright, You will have to pull recoil starter housing off to get to flywheel and magneto.Thickness of emory cloth is ok for flywheel/magneto gap. 4 bolts hold cover and 2 hold magneto. difficult to get cover from behind fuel bowl but it will come off without removing bowl.not a difficult job, takes about 20/30 minutes, and should give you a good clean spark and easy starting for 2 or 3 years.
