Of course not. The octane of a fuel has nothing to do with if it eats gaskets or not. Octane just retards pre-detonation in a high compression engine. Use the fuel recommended by the manufacture. You are wasting your money on any higher octane than the engine needs and getting no benefit. This myth just will not die.
You have to check the fuel pump and the carburetor. (mainly gaskets)
It can be caused by blocked (dirty) carburetor passages, faulty carburetor diaphragm or weak governor spring. Dirty or binding governor linkage can also cause the problem. However the most common cause of surging (revving up and down) in small engines such as those found on lawn mowers, is vacuum leaks. The gaskets often dry up when the engine is stored over the winter with an empty gas tank and then leak air into the carburetor. Prevent this by putting fresh gas in the tank with a stabilizer additive before storing for the winter. To test for bad gaskets, spray starter fluid around the carburetor gaskets while it is surging. If it stops surging while you spray, you have your answer.
The carburetor gaskets are the most likely candidate. The carb gaskets in weedwackers act as a fuel pump. When the gaskets get stiff they no longer pump enough gas to feed the engine. The other possibility is a blocked carburetor passage or jet that is starving the engine, but my craftsman weedwacker had the same problem even after I cleaned the carb thoroughly. The gaskets were the fix. You can either have your carb serviced at a local lawn shop or if your good with small parts you can buy the kit and DIY.
Yes
Floats could be stuck, check for dirt or sludge in the bowl and around the pivit points of the float, clean entire carb completely or gaskets are bad, buy a rebuild kit and rebuild the carburetor, the instructions that come with the kit make it fairly simple task.
Having water in the gas tank will work its way up to the carburetor.
Gas is not getting into the carburetor because no Saturn made ever had one.
Yes, injected engines do not use a traditional carburetor. EFI gas engines do not have a carburetor, and diesel engines do not use a carburetor.
(No Charge)First test the battery. If it is OK check the alternator. (Die at stoplight)Start with a good tuneup (plugs, points, rotor, distributor cap). If that doesnt solve it, either replace the carburetor or rebuild the carburetor. It sounds like it is staving for gas at idle which could be a minor carburetor adjustment.
A carburetor regulates the flow of the air/gas mixture into the pistons of a gas engine. They aren't found on cars any longer but do still come into use for smaller gas engines.
