I am just now learning the 2002 3010 I got from a friend that had sit up for 3 years. Changed out all the fuel lines, filters, pump and cleaned the carb. I have gotten it running but not correctly just yet. It will run fine as long as I keep some choke on, but will die a few moments after I release the choke. I suspect the fuel pump but I do not understand its operation. If you have other ideas, I welcome them.

The main reason for my post is that I do not understand the fuel pump operation. When does it run and what turns it on? Does it run with the ignition on and not cranking? Does it run when cranking? Or only running? Can I test its function by running line into a can while cranking? As you can see, I am a bit lost with this......

 

The fuel pump runs when you turn on the ignition key. Usually it works or doesn't. The fuel pump is unlikely your issue.

I suspect you have a clogged low speed idle jet in your carburetor. You'll need to disassemble and clean your carburetor. Remove the idle mixture screws and spray carb cleaner throw the jets and verify there are no blockages. Before you touch or remove the idle mixture screws, screw them in completely and count the number of turns it takes to bottom out so when you reassemble everything, you'll have the air/fuel mixture exactly like it was. I usually paint a dot on the screw head and carburetor body for reference.
