My lawnmower will only start with starter fluid when sprayed on the filter. But it just runs a little while. It has a primer bulb but that doesn't start it. I took the bowl off and cleaned it out. Is there someting else I need to check? This is my first time trying to repair it by myself. Can someone please give me some idea.
Thanks
Lisa

If it is the bowl type, remove the bowl and there will be a circular ring on the bottom. This is called the float. Follow the float to the top and there will be a small pin that plugs into a even smaller port. This is called the needle valve. Make sure this whole component (float and valve) move freely and are not stuck. Fuel fills the bowl and as the carb uses the fuel the level decreses in the bowl, lowering the float, opening the needle valve, allowing more fuel to flow into the carb. If its stuck fuel will not get into the carb. Usually these older styles do not have primer bulbs though. Newer carbs with primer bulbs haver a carb that is mounted on top of the tank by 2 screws. Remove the 2 screws and lift the carb out. Lift it straight up because there will be a dip tube that sits inside of the tank. This is where fuel enters the carb on these newer type of carbs. Be careful they are plastic. The end of this tube will have a fine screen. Make sure the screen is clean, if it is blocked fuel will not enter the carb. Try spraying with carb cleaner when you remove any of these assemblies. You only need three element to start a engine fuel, air and spark. Since it runs when you spray the starter fluid you definitly have air and spark, you just need the fuel to enter the carb. The fuel is blocked somewhere.

never use starter fluid on a small gas engine. Make sure the air filter is clean. make sure you have fresh gas in the tank get rid of the gas in the tank replace with fresh then remove the spark plug and put about a teaspoon of gas in the chamber and put the plug back in and then try to start the normal way. make sure the spark plug wire is on plug correctly. also after trying to start it for a while take the spark plug out and shove the head of a wooden kitchen match into the spark plug hole if flames blow out the mower is getting gas. there can be alot of reasons the mower won't start. such as a sheered key or vent could be clogged or a bad coil. did the blade hit something hard?

You have one of two problems,, the primer bulb may have a pin hole or crack,, replace!! or the diaphram maybe dried out! Todays small mowers do not have the big complicated bowl carbs,, just little suction types that use a diaphram. These are easy to replace if you are good at putting things back exactly as you took them apart!! best if you have someone do it for you and ask to watch and learn!! if you use a gas preservative in your tank before storing the mower,, you will not have this prob later!

Check the air filter by removing it and seeing if the mower runs. Remove the spark plug and clean it with a wire brush. If none of these or the answers already suggested don't work take it to a shop, that is if it's worth it.

First check the owner's manual, for trouble shooting tips. There are several things that might cause this, needs a new sparkplug, fuel filter needs cleaning, or the gas is old. You might even have some water from condesation in your tank.

Your doing it right. Add the oil slowly and check the dip stick. Too much oil will cause excessive oil pressure. A new dip stick may be necessary. It is also hard to read many dipsticks with light colored oil. And my last two cars took a while until the oil drained to the oil pan to be properly read. Meaing the oil level could wrongly read as low. So i have to wait like 30 seconds to read the dipo stick after pouting the oil in.

Sounds like the screen on the fuel pick-up tube in the gas tank
is clogged. Just had to clean it on my own mower!

depending how old the mower is, you should have an idle screw you can adjust, or there may be trash in the carborater, is the gas in the tank fresh?? have you checked your spark plug? it may need to be replaced. congrats on doing it yourself.
