98 z440 won’t idol

Oil is blown all over front side of cylinders and bellypan, changed out cylinder gaskets. Sounds like it’s running on one cylinder, but both sides have compression and spark. And I changed the plugs out so ruled out fouled plug or bad piston. Drained the gas tank & refilled. Blew back fuel lines past the filter and pump. It will run good over 4rpms but anything close to idol speed it will shut off almost instantly. Not too sure wht to look at next

Pilot jets are clogged. Smallest jet next to main circuit, hidden down a small tube. Pull em witha small flat blade screwdriver and clean until you can see light through the tiny orifice.
