[QUOTE="jmics19067, post: 793530, member: 27963"] this is what I would belive to be correct. although I may not be 100 % accurate in the scientific explanation of things the general blanket statements would be true as well as the idea behind it. spooge is incomplete burning of the gas/oil mixture and spark plug fouling is caused by the tip of the plug not being hot enough to burn off any deposits left over from the combustion process. the gas/oil mix in your tank is an apple, the air/fuel mixture in your combustion chamber is an orange both are needed to make the fruit salad appetizing but they are different. you need the proper air/fuel ratio to burn all of the fuel and consume all of the air at the right time to make the best controlled heat which is the source of power that pushes the piston down. Too much fuel and the tempature drops, losing power and leaving unburnt fuel.Ever burn leaves in the fall? You have a small fire and you throw a large pile of leaves on the small fire you choke off the air and all you have is smoke until the air flow can can catch up to the fuel(leaves)trying to burning. Too little fuel and the tempatures go up uncontrollably ,think of a cutting torch when you hit the oxygen lever. In your gas/ oil mixture the gas is the fuel in the fuel air mixture.The gas is readily burned when mixed with air and the oil will burn when the tempatures get hot enough for it to flash.32-1 is 32 parts gas to 1 part oil 40 -1 is 40 parts gas to 1 part oil. so for every measured drop that goes thru your carb the 40 -1 will have more gas in it than the 32 - 1.That could easily aggravate the problem of too low of combustion tempatures resulting in more unburnt spooge and fouled plugs. Where if you adjust the carburator so less fuel goes in the combustion chamber for a given amount of air where all of the fuel is consumed tempatures go up consuming the oil and keeping the plug tip burned clean. so you want enough oil to protect the engine then the right fuel air mixture to burn everything clean in a safe, controlled, consuming all ingredients, burn. does that make sense a heck of a lot easier for me to visualize it than to type it [/QUOTE]
