You will have to give us a lot more information before we can provide you any help. We hate making guesses when we don’t have good information. Please provide us with the following.
1. We need all engine numbers, model, type and code.
2. How long has this been going on?
3. Has the unit been sitting for an extended period of time?
4. Has anyone tried to fix the problem. If so what did they do?
5. When was the last time the engine was serviced?
6. What are your mechanical skills?
7. Have you removed the fuel line at the tank to check fuel flow there?
8. Have you check for debris in the tank, blocking fuel flow?

When we get this info, we will have a better idea how to proceed. You need to help us before we can help you.

It was running fine. Sat for 3 weeks. No one but me has worked on it.

Boy I didn’t think these were hard questions, but you only answered two of them and that doesn’t offer me a lot of help. Can you answer them all in more depth? If not I can’t be of much help.

If you are saying that fuel trickled out of fuel pump with line removed going to carburetor, when you cranked engine, then you need a new fuel pump. Fuel should shoot out with a nice steady pulse.

Only if your fuel line is not blocked.

And there is fuel in the tank. Just saying........

Sounds like fuel can trash blocking the tank nipple or the inner rubber of the fuel cap is coming apart and is now got bits of it in the tank. If you have to run it with the choke on, there is a fuel starvation issue.

Could be water in bowl. Do simple test first. Take carb bowl off dump it and wipe it out. Put back on and try again. Just a couple drop of water can cause this to happen.
