Introducción
Esta guía toma un poco mas de trabajo que otros remplazos de la podadora. Primero remueve el filtro de aire y luego ve detrás y remueve y limpia el tanque carburador. Utilizarás una llave de tubo con 5/16" y 1/2" de Hex Bit y una herramienta de palanca. Antes de comenzar, tal vez necesitarías compra un O-ring si tu podadora es vieja, ya que el O-ring de tu podadora puede que esté desgastado. Limpiar el carburador puede ser un poco sucio, así que no lo intentes adentro.
Qué necesitas
-
-
Usa un destornillador de cabeza plana #4 para remover los tornillos de 40mm que sostienen el filtro de aire en su lugar.
-
-
-
-
Utiliza una llave de tubo con una punta hexagonal de ½" para quitar el tornillo de 11 mm en el fondo del tanque.
Yes, definitely clamp off the fuel line with locking pliers. I can’t believe this guide would neglect to mention that.
Also, I would not call this a “tank” — it is not the fuel tank. Everybody who works on small engines calls it a fuel bowl.

Una vez que retire el perno del fondo del tanque del carburador, abre suavemente el tanque con una espátula de metal hasta que se suelte. Si no tienes un spudger, un destornillador de punta plana funcionará.
-
Retira completamente el tanque para poder limpiarlo o reemplazarlo.
The thing that is most important to clean here is the screw in the bottom. It has holes which, if clogged, will prevent your engine from running for more than a second or two. Make sure you clean them out with carburetor cleaner. It's easy to miss, as it falls out into the socket when it's unscrewed.

Your old post on cleaning the float bowl retaining nut was a real problem solver for me. Had done everything but clean n the flow thru holes in the retaining nut. Reassembled and mower engine started right up. Thanks a lot. Sam
Yes, definitely need to clean out the ports in the bolt with a needle, can’t believe that’s not included in a guide about maintaining a carburetor.
Similar comment to previous step, it’s a fuel bowl, not a fuel tank.

Inspecciona la junta tórica dentro del tanque del carburador. Si está seca y desgastada, es posible que debas reemplazar la junta tórica antes de volver a ensamblar tu dispositivo.
Is there a filter in the bowl? I see something and it is covered with junk. Wish there were a schematic.

Nice guide. My mower was only running on choke, any other throttle setting and it would die. A quick online search indicated dirty carburetor and subsequently I found your guide. Gave everything a good clean and voila! Good as new.
Slide clamp on fuel line back and pull fuel line off carb. plug line with old pen/pencil
Remove two nuts holding carb onto engine. Remove nut holding engine choke arm on top of carb. Then remove two springs and one carb adjust metal arm. Note places of attachment
spray cleaner in all brass jets, use fine wire to clean out all orifices, clean bowl attachment nut. Spray cleaner in to choke area and tip upside down and spray under the bowl needle.
drain old gas out of tank and alternatively add a in line fuel filter as well a new air filter.
clean or repl spark plug
Excellent suggestions, as well.
yes, this is a better guide for cleaning. the other should be called "how to inspect your carb O-ring"

took off cover, that plastic washer was cracked. what is the part number for that? i need it replaced as this is where a fuel leak was happening.
Excellent directions, but I have one minor critique. There is a lot of gas that leaks out when doing this. Maybe, suggest pinching the gas line? Otherwise, this was great!
Have tried everything else before finding this site. Following these instructions will be my last attempt before beating my daughter’s string trimmer to absolute and irredeemable destruction with a sledge hammer. I have a feeling that following these instructions will work and save my daughter a lot of money.
I carried out these steps in addition; maybe they should go without saying but worth it all the same.
Before step 1, clean the external area well (I use carb cleaner spray) to remove the crud that builds up in the nooks and crannies and won’t contaminate the carb/air/choke areas.
Before step 3: Clamp the fuel line between the tank and the carb, in case there’s some gas left in the line and the tank. I have done this several times with a partly filled tank and without removing either end of the fuel line; anything to make the job easier.
Before step 5: Stuff some rags or paper towel wad under the tank to catch any residual gas that drips out.
how to slow rpm on engine
I would add that the hex head at the bottom of the bowl is also the main jet…using small wire and carb cleaner to make sure ports are clean. I have three port holes….one that rums all the way thru the sides and one at the bottom of the bolt. I came here to try to verify that the one at the top if it connects to the ones on the side….either it doesn’t, or mine is clogged.
I have the same model lawnmower. The problem I am having is that the when I full the gas tank all the gas leaks out through the little hole on the priming bulb. My lawnmower usually sits for months at a time without use. Do I have to replace the pin and seat kit?
Replace the primer bulb.

Parts are cheap off of Amazon if you need gasket or bowl O-ring. I got bowl, gaskets, O-ring, needle and more as part of rebuild kit for $9.99 and free shipping. Sears wanted much more.
