yes..return presure line submerg dosen't help.

try leaving the driver on a a little bit longer to let the engine warm up.
then lean it a little at a time.

when the engine dies when you remove the glow driver.
it's either too rich or the plug is fouling out.

if it's the same plug you had in the engine while it sat.
gunk or oil resedue will form on the plug's coil, thereby not allowing the plug to get hot enough.
