Toro Lawnmower Carb Questions Re Cleaning Of ?

[Robert11]

Hello,

Thanks for previous help with all of my questions. Much appreciated.

I have a 10 year old Toro self propelled 22" GTS Lawn Mower. Tecumseh engine.

If I prime it, will run for about 5 seconds; than quits. Each time the same. Won't start again, unless re-primed as before.

Probably a gunked up Carb., would be my best guess.

Not too sharp with this kinda "stuff," so please bear with me.

a. I removed the bottom brass screw from the Carb. bowl, and cleaned out the transvers holes, and also the axial one.

Question: on the top of the screw (the end away from the threads), in the center there is a bright metallic "dot" or very small round metallic insert. Maybe 1/32 or so of dia. What is this, please ? Seems to be in very firmly.

b. I ordered a can of Sea Spray cleaner.

Really don't want to have to take the Carb off, if I can help it.

Can I get to most, or all, of the ports, etc. from the Carb bottom now that the bowl is off ?

**If so, how can I identify what to spray into ?

Or, must the Carb truly come all the way off to get at these, presumably gunked up, ports ?

c. Should I also spray into the air cleaner intake (filter has been removed) ?

What is the small red tube sticking out of it ? Should I (also) spray into it with the Sea Spray stuff ?

Anything else to spray with the solvent ?

Much thanks, Bob

e center there

32 or so of dia.

This is the end of the main jet adjustment screw, the end that is outside? Never saw anything like that.

You can clean it when it's apart with carb cleaners, brake cleaner, etc all available at auto stores, Walmart, etc.

You can't clean it completely without taking it off. Also many carbs have w elch plugs that cover passageways and you have to take them out to clean it . They are one time use. There are carb rebuild kits on ebay that give you those, new gaskets, needle valve, etc

at the bowl is off?

No. It's not hard to take the carb off, at least most carbs.

gunked up, ports ?

Idk
