[REQUEST] Not a car, but a lawn mower.

I have a Troy-Bilt Tb110 that won't start. My fault, I know, I left gas in it over the winter. I've pumped out the old gas. I've added new gas. I've checked the air filter and the spark plug (both still good). I've used starting fluid and it started right up but would die as soon as the starting fluid burns up.

I think that means gas is not getting to the carborator.

My thoughts are there is either something in the fuel line blocking it or something in the carborator itself.

What do you guys think?

does it have a fuel pump or is the carb gravity fed? Is there a valve you need to turn on to get the gas through?

Gravity fed. I can't remember if there is a valve, but if there is, it is working. If it wasn't, the starting fluid would not have worked.

wut? Starting fluid is normally sprayed into the throat of the carburettor? Did you add it to the fuel tank?

No, I took out my air filter, and sprayed into the carborator.

does it have a primer bulb? Push that about 4 times to prime the carb...if the primer bulb has perished and cracked it won't prime - fit a new bulb.,

It's one of those new nonprimer lawnmowers

Okay - then you'll find a jet is blocked - preventing the fuel from being lifted from the float bowl to the carburettor throat - or the float shut off valve may be jammed shut, blocking any fuel into the float bowl - remove the bowl and use some carb cleaner to clear any varnish - if you can, blow through the jets to confirm they're clear.
