If it was running before the change and not now. It's probably either the petcock or you dislodged some crud in the tank when you did the change.

I'd disconnect one of the fuel lines coming off the petcock and see if you're getting gas through it. Good luck with it

Make sure the hoses are in the right places.
Have to say it, you did put gas back in the tank right?
Did you check if you have spark, could have bumped a conector when taking tank off.

What I would do:

Hook up a spare fuel line to one of the fuel outlets - apply vacuum to the vacuum port (either by cranking the starter or a syringe or mityvac or the like). See if you get fuel. If you do, try the other hose and do the same.

If ya dont then go farther with diagnostics.

It does sound like you may have allready done this?

Make sure your battery is fully charged - sometimes a battery being kinda dead can cause starting issues.

If it's smelling like it's flooded, I'd definitely check your plugs - you may have flooded enough to foul the plugs...

Just some ideas...

yeah been trying it on and reserve. I gave up for today but tomorrow I will try some new ideas. I think I need to prime it or something. It must be so dried out. Anymore suggestions would be appreciated.

Jake -

It could take a couple or three 15 second runs on the starter on full choke before its going to fire. Don't crank more than 15 seconds, give it a rest and go again.

Kill switch?
