Engine will not stay running

check and make sure its getting fuel. when trying to start, spray some engine starting fluid in spark plug hole. just a little bit. replace the plug then try to start it. if it starts then quits then its a fuel problem. fuel not reaching engine. good-day !

Did you check the filter? If the engine doesn't get air they it could cause it to die out like that. Also make sure that there isn't anything in the air line to the carb.

Did you check the gas line and make sure that you are getting enough fuel?

For the easiest solution, try running some automotive type fuel system cleaner through the machine (added to the gasoline; not straight). Find some Chem Tool Berryman B-12 at the auto parts store and add 2-3 ounces in a gallon of fuel or 1-2 ounces in a half gallon. The solvents in the cleaner may aid in cleaning a dirty carburetor. You may want to drain the fuel and remove the carburetor bowl and clean it out as debris may be there, intermittently clogging up the main jet in the carburetor. Water will settle there too.

Is there an easy way to install rotor blades on a Toro Model 38430 snowthrower?

make sure you are using the correct fuel/oil ratio. change spark plug

Fuel Starvation - Float Bowl Carburetor
1) remove air filter assembly
*be cautious of tearing the mounting gasket. If it does tear, you HAVE to replace it. It is part of the priming system
2) remove the float bowl fastener. This is the main jet
3) carefully remove the float bowl, the rubber o-ring/gasket will not be able to be used if it is removed, you WILL have to replace it
4) using a spray 'carb cleaner'
spray up thru the center of the carburetor
spray and clean the main jet with cleaner and 'tag' wire
(tag wire is very thin, and can be used to clean the hole in the center of the main jet)
5) clean any debris from inside the bowl or carb body
6) re-install bowl and center bolt, air filter assembly

*if you need gaskets, your Briggs dealer can supply. The kit is cheaper than individual gaskets, and all the parts needed to finish the above repair are in the kit.

cleaning the carb might work soak it in gas foe a lil wile and it may fix the problem

The problem is that the gas that sat in the carb all winter glazed it over and gummed it up. Begin by going to any auto parts store, like an aiutozone, and getting a bottle of carb. cleaner. Seafoam is one I use. Add it to your gas, one ounce per gallon of gas. Also, pick up a can of engine starting spray.

Remove the air filter and spray the engine starting spray into the air intake. Pull start the engine and give it additional squirts of engine starting spray until it runs smoothly.

hi paul,

sounds like you have a dried out diaphram in the carburetor. depending on your model mower it will be located on the carburetor on the side attached by screws or it could be on older mowers underneath the carburetor if the carb is mounted to the tank. in any instance priming the bulb then it dying out is a sur indication of this. i woild replace the diaphram (inexpensive fix) cople dollars or so and that should work. you can take wd 40 and spray carefully around the carb base or around the cover to the diaphram and see if it will run a little longer if it does sometimes this will lubricate a dryed diaphram and will allow it to continue to run at leastuntil it becomes dry again. but it may allow you to get some mowing done until you can relpace it. hope this helps!

If it is leaking when priming then you have either a cracked gas line or bad seal. the most common issue is a cracked gas line. This is a easy fix. You can get gas line at almost any hardware store.
