On a 74 Corvette, there is a primary coil inside of the distributor that is usually the cause. I would assume that the engine turns over, but no fire. While you have the distributor apart, you might as well replace the secondary coil, located under the distributor plate too, because if this is the problem, you would have to tear the whole thing down again to fix it, and the parts do not cost that much.
No, contacts do not cause acne.
Take off cap, check for slack in dist. bushings, See if the shaft can move side to side?, I bet so, Replace the distributor.
The magnetic plate in the distributor shaft, for the pick up coil, may be cracked.
Try a minor tuneup by changing the spark plugs and checking the distributor contacts. Sounds like the vehicle is burning rich which is what's making it shake and finally stall while stopped. Dirty or worn out plugs or even a bad spark due to corroded or dirty contacts in the distributor will cause this.
A person's eye color cannot be changed in any natural manner. The use of colored contacts can cause eyes to appear darker.
Certainly. Check the inside of the distributor cap for any indication that there may have been "electrical arcing". Moisture too can cause backfiring. If you haven't changed the cap and rotor for a while it's not a bad idea, just out of preventative maintenance.
yes.
Most likely cause is an inoperative condensor fan.
You must have an antique car. I haven't had a car with a distributor in 30 years. Remove the distributor cap and examine the four or six metal contacts inside for corrosion. The contacts are shaped something like tiny straight-back chairs. The backs of he chairs often corrode. If you see corrosion you want to scrape it off. I used to use a flat blade screwdriver. If you can get a razor blade inside the cap without scarring something you could use that too. Try to avoid scarring or removing metal from the contacts, 'cause this can screw up the cap. Do a similar thing to the end of the rotor -- the part that swings around to deliver spark to each of the metal contacts. Again try not to remove metal -- just corrosion. See video in related link below.
While some questionable places will sell you contacts, if it is a new prescription, you should have your lenses fitted. Contacts are not like socks. They must fit your eye or can cause plenty of damage, irritation, blur and pain. The difference is clear. (pun intended!)
The oil and acid from your fingers will cause the gold contacts to corrode.
