It will only run when u squirt gas in the carb it runs good then but once the gas is gone is shuts off

Check to see if the vacuum advance rude came off !! Or check to see if distributor is stuck so that the advance is not working and it in the advance stage causing it to try and fires to late !

Hi Joe:
Don't know what "it" is, but the fuel pump needs to cycle enough to prime, the carb or injectors need to be filled with fuel.
If it is a carb, remove the air filter and look into the carb...... pump the throttle linkage...... the accelerator pump should squirt gas into the throat of the venturi. If there is no gas, a squirt of gas to prime won't hurt.

Runs that rough after sitting 5 years? Don't even second guess it: get a rebuild kit to replace all gaskets and rubber parts. 2 or 3 cans of carb cleaner to really clean it well and all passages in the casting. Don't bother with the carburetor dip-it's been so sanitized and leaned out with all the regulations, doesn't do as good a job as it used to. Aerosol cans of carb cleaner with the tiny tubes for cleaning out those little passages.
Start off with a known good carburetor. Use fresh gas, too.

If the fuel bowl is full of gas the needle seat assembly may be at issue. Make sure the float level is correct. If set too low, the seat will close and not allow fuel to pass through. A carb rebuild may be in order.

What type of Honda is this? Not sure what an EX1000 is. Is it a motorcycle?

get a oil can the thumb operated type and squirt some oil down the petrol pipe and make sure pipe is upwards so the oil runs into the pump then leave for a while to wet the valves in the pump then crank engine to make sure petrol comes up or just refit the pipe and pour some petrol down the carb and watch it go

Okay, your freind may be right, that part is called the accelerator pump, it is used for starting the truck, when you pump the gas to start it this pumps a few squirts of gas into the carb. what concerns me is that you hold the gas pedal to the floor to start it, most of the time an internal leaking carb floods the engine and holding the pedal down will let it start, a quick test would be to use a carb cleaner spray and before trying to start the truck hit the gas pedal and see if inside from the top of the carb look and see if you see a squirt of gas spray out, you will need some one to push the gas pedal or you can do it at the carb, if it squirts gas then the accelerator pump may be good and carb may be leaking and need rebuilding but if it doesnt squirt then its bad and then i want you to spray the carb cleaner into the carb and try to start the truck and if its due to the accel pump then after you spray into carb the truck should fire up and run without having to hold the pedal to the floor, if thats the case then replace accel pump if it still doesnt fire until you hold gas down then crab needs rebuilding . good day. hope this is helpful.

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?

after it has shut down check for gas at the fuel rail with the key on their should be gas squirting out constantly it sounds like the fuel pump is going out

clean the carb jets,they are blocked

Do this, take the top off the carb, being careful not to damage the gasket. Then take some carb cleaner and clean out the bowl and floats. Remove the needle valve and clean it out. Put it all back together and filling the bowl with carb cleaner. Start it with the starting fluid. Once you run the carb cleaner through it, it should start to run on it's own. Whatever you do don't shut it off for about 20-30 min unless you have to.
