Normally this caused by a leaky float needle valve in the carburetor; although, if you have a vacuum operated fuel pump it internal may ruptured.

Usually is a bad float valve needle and seat in the carb. Sometimes dirt in the floatbowl will cause this too. The correct thing would be to replace the needle and seat in the carb.
A temporary fix would be to turn the gas supply off from the tank as soon as you are done using it. If your mower doesnt have a shut-off valve, you can buy one and install it, pretty simple fix.

How can I cheat the Idle up? I'm getting a low oil pressure light at Idle, 800 RPM. I would like to increase the Idle to 1000 to keep from getting the light.

that wont work trying to adjust idle can be done on older cars with a carburetor or the older throttle bodies new vehicles trying to do it will set off check engine lights on most sensors sound more like oil worn out---oil filter or pump problem change oil and filter and do a flush ---and put in an additive such as lukas - royal purple etc---also why did head need replacing was oil pump tested

Why do I get oil on my spark plug?

is it a 4 stroke with an oil pan or a 2 stroke with mixed gas and the plug is getting fouled? if it is a 4 stroke, then it should be stored flat. if it is a 2 stroke that is fouling the plug then it will be a carburetor issue

What is wrong if it will not idle

It would help to have engine codes but it sounds like leaking injectors hard to start because any time the key is on gas is just running into the engine. No idle to much gas. Oil level high because of gas in oil going past rings could blow oil pan off. High speed fine. replace injector or injectors. Look down throttle body with key on and see if gas is leaking out. If this help someone please rate it

My weed eater wont turn on it keeps turning off as soon as turned on it is really frusterating sorry if i spelled that wrong

Most two stroke engines in weed eaters require a premixed fuel combination of gasoline and two cycle oil. I am assuming you have a gas model which needs a gas and oil mixture. A possible problem is the choke is turned on, and once it starts you need to move the choke to run. Another possible problem is the gas oil mixture is incorrect, and you may need to remix the fuel to the manufactures recommendation.

Does the blazer run ok? how much gas is in the oil? You will get a certain amount of gas in oil thats normal. If your getting like a half a quart thats not normal. If your getting a lot in the oil its got to be flooding and fouling plugs. Need the whole story in order to help. Just taking a gess hear its the injection system, there was alot trouble with them thru the years like your blazer.
