Fuel feed Ive cleaned the carburator, changed the plug, air filter, but it just won't take off. It will chug-a chug-achug then die. It wants to go but acts like it is not getting fuel. This is a toro self propelled, walk behind model 20017

Start with checking fuel pressure. Pressure must be at specs before looking elsewhere, like spark plug condition, air filter, air or vacuum leaks, throttle position sensor, etc.

Make sure the fuel jet is clean. Its easy to miss when cleaning the carb. Ive seen a lot of dirty fuel jets that once I clean them out run like new after.

Have you checked your fuel pressure ,Changed your fuel filter, and last of all , Ignition module... free check at Autozone, Advance, Napa,
The chugging- clean out or replace your IAC valve, Idle Air control valve...

Tryd go to auto shop and check the carburator of your motor and clean your air filter adjust air setting in carburator and put a new fuel pump check fuel setting in carburator

When you chaged the air filter & sprayed Gumout carb cleaner, you got rid of a little gunk in the
air intake, but when you added the fuel injector cleaner (its the same stuff as carburator cleaner) to the fuel tank, you "cleaned out" ALL the ****/gunk/buildup/dirt in the fuel system which has built up since 1991 and sent it straight to the fuel filter, which is now clogged. The reason that the car tries to start, but fails, is that it'll successfully burn up any fuel that gets past the clogged fuel filter, but the engine consumes that small amount of gasoline quickly, then dies.
Your solution: change the fuel filter.
The fuel filter is located:
Under vehicle, driver side, below seating area, near fuel tank, mounted on frame rail in fuel line

Clean air filter,Change out fuel for fresh fuel.Check plugs and gap on plugs.You may even have to take off and clean carburator and fuel bowl.

yes please replace the fuel filter,the fuel filter replace every 40,000 kilometers according to the factory specifacation.then buy a repair kit of the carburator to clean and replace gasket to prevent leaking of gasoline

Carburator clean up could help solve the problem, it seems some dirt may have entered the float chamber!
Blow the jets with compressed air.
Hope this helps!

put a new spark plug in
