Sorry to hear that, hope she is feeling well soon!
Spark plug access for my S150 is the same-very tight.
She may have noticed that there is a small plastic cover above the spark plug, about 2"x2" that slides up and out to provide the best possible access.

Thanks David. I'm feeling better now, but I hear the worst is yet to come. The bruises are special colours, and I have less respect for some nurses than before. Sad I work for them, and the batch on my unit last night were less than stellar. 
BAHAHAHA! Nope! No cover on mine! Hatchet job by the last owner I suspect. Lucky me I have Paul's intact mint beauty to compare to.
Two hours to put a plug back in? Ridonkulous! Just could not line it up to catch a thread.
Plug was wet & oily, right up the threads. I'll check the gap and see if I should pull the engine for seals/gaskets etc. Maybe I'll limp along until the fall. Idle is low and a tad rough. Geez, to get the spark plug wrench off… I thought I was going to either have to bust the plug, or over tighten the thing. Design fail. An access hatch might have been helpful.

Our thoughts are with you, get well soon!
The ET4s and all the LX150s I have worked on do not have an access hole. Must have added it for the S150 (which I think is what David has). It is tight. I have special spark plug sockets designed for the tight access around aftermarket exhaust headers. They work a treat, just a few minutes to change a plug.
Before you remove and strip the engine, let me have a look at it! Might be something simple. We were going to get together for a look-see but never did get around to arranging a time. Everything is up in the air right now but I'll know better after Tuesday evening what my schedule is for the next three weeks.

Thanks John! I can wait, I'm in no rush for a tear-down.
Truthfully, not sure I'm in a rush for a ride in the near future either. 
We used the wrench from Paul's under seat kit. I'd be grateful to see what you have/recommend for a wrench. I'm positive my socket would never fit in there. And I'm never averse to buying good tools if I'm going to use them!
heh.
Cheers
