If it is starting and not continuing to run it still sounds as though something is blocking the fuel flow. If the carb has been cleaned out, literally torn down and the needles cleaned so that no small debris is clogging them, check the fuel tank and lines for anything that could be restricting the flow to the engine. Remember that it's recommended that you replace the fuel line (cheap fix) when you dismantle the carb. Removing the line breaks off small pieces of the rubber in a worn line, which can re-block a freshly cleaned carb.

Lawnmower starting problems


Clean or replace air filter. Fill oil, 30w. Clean & gap plug or replace.
Remove carb bowl from bottom of carb & clean. If gas is 30 days or more old, use fresh gas with Stabile.

Clean or change air filter. Clean, gap or change spark plug. Empty gas tank add fresh gas with Stabil. When spark plug is removed pull rope several times to blow out cylinder. Spray starter fluid in spark plug hole before replacing spark plug. Clean outside of carb so choke works freely. Spray starter fluid into carb breather hole with air filter removed and try to start. if running replace air filter and cover. If no start disassemble carb and clean. If no start replace carb.

Lawnmower starts and dies... where is the main jet for the carb?


try cleaning the air filter, then a touch of starting fluid right into the carburator by taking the air filter off. If it then starts but wont run or stay running, the reservoir below the carb should be removed to clean at and the pinhole in the intake tube above the bowl nut. This is the most common problem with lawnmower start problems, the pinhole can be unplugged with one wire from a wire brush. Be careful with the gas, at least pinch off the gas hose with a vise grips while removing the carb bowl.. Never use a droplight around gasoline. most lawnmowers have no mixture adjustments, so it is a matter of cleaning the carb, tank, gas lines. Some oils in gas mix systems settle and clog after less than one season.

Snapper lawnmower will not start - sparkplug is good, air filter clean, no idea what is wrong

Spark can be tested by sight, remove the plug and use a clip-on ground wire from spark plug body to metal on the engine with the plug wire connected.

My Troy Bilt Self Prop. Z-start won't keep running. I clean All, replace Filter and Plug, have clean gas and lubed all. It Starts for 2 seconds and then cuts off. What do you think it could be? Thanks....


I had the same problem, Tilt the lawnmower on it's side air filter facing up and remove air filter cover and air filter then remove the fuel bowl underneath the carb; then clean the fuel bowl with some gas and a clean rag. For the next step be sure to aim blower tip at target then look away before pressing trigger, this will prevent gasoline form getting into your eyes.Take an air compressor and carefully clean out the carb where the flap is and the tube where the fuel float that would rest inside fuel bowl is. Leave on side install everything back except for air filter and cover. Then pour a little gas in the carb to prime it, lay the lawnmower back on all 4 wheels and try to start.

Troy built 6 75 hp lawnmower will not stay on I start it but it will quickly turnoff''


on the bottom of the carb. is a bolt that holds the float bowl on. remove that bolt and float bowl. use a small needle and stick it in the holes on the bolt to clean them out. look at the gas in the float bowl to make sure there is no water in the fuel tank .

Lawnmower starts but won't continue to run


if you are getting no fuel to the plug you either have a stuck float, plugged fuel line or filter. does the gas reach the carb bowl? does the mower have a fuel pump? if so the diaphram might be bad.

I have a ryobi lawn mower with a 6.5 hp motor. it


I am working on one now. Customer said "it doesn't run". Ok. So, after oil/spark plug/air filter replacement...it didn't have any gas getting to the carb. Took off the bowl, and on this 2005 lawnmower, the inside of ALL of the carb was covered with a white/chalky film. Looked like tiny rust barnacles over ANY metal surface available. Silty white stuff in bowl. Blasted it all w/carb cleaner. Still couldn't get primer to work, but after I sprayed a bit o' starter in the cylinder, it started well & kept running. Until I let the bar down. Needs a new carb. Will see what the customer wants.

Try cleaning the air filter, and check fuel tank for any debris.
Replace fuel filter if there is, and give the fueltank a good cleanout.
Use fresh fuel to refill.
