Small Engines (Lawn Mowers, etc.): Coleman Gen-pro 5000 Gas generator, sae 30, oil reservoir

Question
Have a generator that hasn't been used in a good while. Thought I would start it up just to make sure it worked. Tryed to pull - the engine was frozen - checked the oil reservoir and gas/oil gushed out - Also the air filter was soaked in gas. Why would the oil pan have gas in it?  

Answer
 Hello James:

 I have one of these Myself. Did you Forget to Turn Off the Gas Flow to the Carburetor when you Finished Using it Last? If yes, then that is Why the Gas is in the Oil. If By Chance your Generator Doesn't have a Cut Off, then you will need to Install One. Change the Oil and Allow the Crankcase to Vent to Atmosphere for at Least 24hrs before Refilling with SAE 30 Engine Oil. If you Don't, then there is a Chance of Blow By to the Crankcase and Usually this is Not a Good Thing to have Happen. The Carburetor Float Needle on the Small Engines of Today have Problems with the Float Needle Not Seating Properly and Leaking Gas into the Carburetor Throat when the Engine is Not in Use. If the Carburetor Seems to be Running Rich Once you Get it Started, then you need to Clean and Rebuild the Carburetor and Replace the Needle and Seat and Other Internal Components that are in the Rebuild Kit. Hope this Helps. I am here if you Require more Assistance. Thanks.

 Good Luck

 Respectfully
