Let it run out of gas before putting in new premium or drain the other gas out. Premium gas won't ignite any easier than regular gas in a lawn mower engine. Premium gas has a higher octane rating which means it suffers less preigniting from the heat of compression in high compression auto and aircraft engines. It'll just waste Betsy's money, Benzette Jeff Jeff is right, the difference between regular and premium is minimal. And to be honest, as most gas stations sell such a small amount of premium gas compared to regular. The regular is usually fresher and still fully potent. Many times the premium is already weeks old, and slightly dead. People who have high compression engines that need the premium will know what I mean. But at the low compressions in a lawnmower it doesn't make any difference anyway. Save the 20 cents and buy the regular. But you can add a very small amount of gas line deicer (PURE methyl/ethelene hydrate/ alcohol) if you have a bit in the garage. (NOT the rubbing alcohol from you medicine cabinet that already contains water) But mix it into the gas can as you only need a few drops per lawnmower tank full. (quart) It helps the gas fire a slight bit hotter and help pass any water/condensation/scale through the carburetor It may not help with your starting, but it can't hurt it. Then pour the rest of the bottle into your car gas tank. It may not pay to fix it, but I would bring the lawnmower somewhere else to see if anyone else can locate the problem your neighbor seems to be missing. It could be, dirt in carb, bad/ misadjusted/weak ignition module, pinched spark plug wire, bent flyweel key, bad plug. But it's impossible to tell from a usenet post. These things are almost all cheap for parts to fix, but labour could cost $100 or more. It would help to know if the motor is a briggs & stratton, tecumeth, or some other make, but I'm going to assume Briggs. Offhand I'd check the spark plug wire is not pinched/cut in the starter-flywheel shroud where it goes out to the spark plug since that was removed shortly before the problems began. (to change the pullcord) Even an experienced person can do this easily if they aren't careful as there is only a slight bend in one spot for the wire to pass through without being damaged If you can get the mower into the dark, try to start it and watch to see if little faint blue sparks may be going right through the wire to the engine case Depending on the mower this wire can be part of the coil assembly, or replaceable separately. And sometimes just a bit of black electrical tape/shrinkwrap over the wire can get you going again. But as already said, this is just an internet guess. AMUN |
