Even then I shifted into the wrong gear (missed reverse - into second), but I don't think he noticed and I didn't make the correction. ;-) He took a couple of points off for crossing the center line on a turnabout (impossible to do otherwise with that car, on that street/driveway), where others were failed the same mistake. My son had it "easy" though. He took his test in my '93 Eagle Vision TSi (power everything, 300HP - don't stick the foot in the gas ;). During the road test the #1 plug wire decided to open[*]. The examiner asked if there was something wrong (a mechanical failure was an automatic fail). The kid said that he didn't notice anything and continued on. [*]That car threw the #1 wire once a year. They were a PITA to replace with garages charging up to three hours labor. I got it down to 45min. The last time it happened I figured out why. The specs printed on the engine called for a spark gap of .062". The shop manual called for .035". -- Keith

I have a set of metric, inch, numbered and letter bits; with those bits, I can gauge just about any size imaginable. And I sometimes actually use the bits to make holes... make them do double duty {;>) The solid end of the bits are very close tolerance too.. probably closer than many feeler gauge sets. -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Never take a laxative and a sleeping pill at the same time!! |
