Back to basics ... Make it fire first, then worry about the little tubes, cold start etc. Very hard to say what works or not if it doesn't fire. If it is not firing when primed, check all of the electrical. Do the plugs spark? Are you sure it if firing number 1 cylinder at the top of the compression stroke? What has been changed or fixed since that engine last ran? The only thing that sounds for sure is that the fuel pump works. Did you drain the old fuel out of the tank? Try starting fluid, available at all auto parts stores in a spray can (It will fire with almost no compression and very little spark).
