Here is my story...
I have an 81 (original owner) with only 24,000 km. Due to family reasons it had been sleeping in my garage (not heated) for the last 5 years. It just sat as is under a cover, without ever starting it...
This summer I finally got to it. I drained the gas out, changed the oil/filter, spark plugs and got a new battery . I unpluged the pink wire from the coil going onto the distributor and ran the starter several time (6-7 time) for no more than 10 secondes each time until the oil gauge was flickering. I then waited for about 15 min for the oil to wet everything, pluged the pink wire back on the distributor and she started within half a turn. Got a bit of white smoke for a few minutes then back to normal. I added air in the tires, checked a few things then went for a ride. It now runs just like I left it several years ago.
May not be the best way but it worked for me... :confused
