If you have no spark, check the ignition coil and ballast resistor.
If the engine tries to fire when you turn the key to off position, there may be a short in the ignition switch.
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.
A person's eye color cannot be changed in any natural manner. The use of colored contacts can cause eyes to appear darker.
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.
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.
No, it will not.
Most likely cause is an inoperative condensor fan.
The oil and acid from your fingers will cause the gold contacts to corrode.
they can cause some irritation
