Usually a Honda that takes a little longer to start, after setting for awhile can be caused by:
1. Leaking injector
2. Fuel pump - there is a check valve in there to maintain pressure after shut down.
3. Fuel pressure regulator - it's failing causing the pressure to bleed off.
4 Plugs & wires - which you have akready re-placed...
As far as the rotton egg smell, most of the time that can be realated to running a little to rich. Might have the fuel pressure checked, this could also be causing the above mentioned...
Just some thoughts...
