To reach your plugs........

[yetibone]

I did the same thing to make it easier to adjust the carbs. I sometimes drive in rain and stuff so I drilled round holes about 3/4" diameter, 2 5/8" apart, and closed them over with rubber grommet-type plugs from Home Depot when I'm not tuning.

Never tried that for plug replacement. I always used a super short 3/8 ratchet, and stuck my arm, elbow and all, down behind the fan shroud. I use my right arm on the left side, and my left arm on the right side for removing #1, and #3, but I've got some pretty long, skinny arms though, and it's not too bad for me to reach.

I think the plugs on a TypeI are about 6" or 7" apart. You will need to measure for yourself to be sure. The diameter of the holes would need to be slightly bigger than a 13/16" spark plug socket, and drilled about 2" above the little shelves in the sides of the compartment.

Even better, cut a larger rectangular blow out pannel to access plugs, and mixture screws, as oval55 described. That would be easier to return to original condition if needed. Mabye 2" above the shelves, 6" foreward from the rear apron seam, and a rectangle about 4" tall, and 8" long. (you WILL need to measure for yourself, as your Bug is much earlier than mine and the engine compartment dimensions are different)
