I checked the gas line to the carb and it's getting gas to that point, if I pour a little into the carb it will start up and run until it uses up what i poured in, as I crank over the engine you can see it's not getting any gas. It's a 18 horse motor on a ridding mower.

obviously it's not getting gas. remove the carb and recheck it. some have a plastic piece over the intake and output to keep the interior clean during transit. Forgetting to remove it will cause it not to get gas. Either that or the float is stuck closed, something like that. If the carb is new out of the box, they sometimes have a piece of plastic or something inside the float bowl to keep the float from banging around during shipping ect. Check that too.
www.repairclinic.com/.../Model-358794762-Craftsman-Leaf-Blower-Par... This part fits your Leaf Blower. Husqvarna fuel filter. If the fuel filter is clogged, it willrestrict the flow of fuel to the carburetor. As a result, the engine may not start.
Make and Model, year of vehicle?
I'm assuming the vehicle won't run unless you pour gas into the intake. If the vehicle will start and run while manually feeding gas to the engine, you can rule out spark and timing issues. Usual suspects in fuel system are dead fuel pump (electrical or mechanical?) clogged delivery system ( fuel line, filter, injector or jet) or intake leak (bad gasket or seal, vacuum leak, stuck valve).
by any chance welder has set for a while, or maybe got water in feul , simply drain carb, drain located at bottom of feul bowl, notice if water comes out ,its normal to get a little water thru years of use , try to drtain in container if possible, replace feul filter , and try to clean feul bowl out best you can , give it a try
This truck is fuel injected, the problem sounds like a weak fuelpump, it runs when you pour gas into it until that gas runs out, the first thing is to test the fuel preasure, if the pump is weak it may run with gas poured into it but wont idle, also a common problem is the coolant temp sensor and the ground wires to thermostat housing bolt but i wont bet its the pump inside the fuel tank, if you put a fuel gauge on it there should be at least 55-61 psi if its a few pounds lower it can cause problems, you have everything else and it runs with gas poured so its a fuel problem check the preasure, theres a valve up top on the fuel line to connect a fuel gauge to it, start there hope this is helpful.
It is a diaphram carb. Doe's the primer **** straight gas or does it have air bubbles in it? If it has bubbles in it then it is a leak in the fuel line.
If not then Unhook the intake fuel line and pump the bulb until all of the gas is out of it. Then pour the gas out of the tank and rinse it out with new gas. Pour in new gas and it should be ok.
It sounds like it's not getting fuel. Are you in a cold climate? The gas line could be frozen. You can check the fuel pump by disconnecting the gas line at the carb, you may want to put a length of hose on the line and catch the gas in a coffee can. Then have someone crank the engine while you watch to see if gas squirts out of the line. I wouldn't use too much starting fluid, you can damage your engine, pour a little gas in the carb instead. Also, on a truck of that age the gas line could have a hole rusted in it between the tank and the fuel pump. If that's the case the pump will not pull the gas out of the tank it will draw air instead. It could be the fuel pump itself. If you have a good stream of gas to the carb then the problem is in the carb. It could be the needle valve is stuck shut, take a screwdriver and lightly tap on the carb, that will sometimes jar the needle loose. If you have gas to the carb it could also be clogged jet inside the carb. I you hold the choke partialy closed will it stay running then?
there are 2 sensor on the carb . you may need to replace both to find out whiche one it is . try this also give it gas while starting and when it starts you will have to keep your foot on the gas a little to keep it running if it runs that way its one of the 2 senors .
