Take an old spark plug from your box of spare parts that you "might need someday".Today is the day.Cut the crimp off just above the hex with a hacksaw.Cut the ground off and drive out the porcelain being careful not to damage the threads.Scrape the hole out clean.Now you'll need about 5'of clear vinyl hose (I used 7/16 o.d.x 5/16 i.d.)and a grommet to use as a seal.Slide the grommet onto one end of the hose and insert this into the large end of the sacrificial plug.BTW you can click on the photo to enlarge.

Remove all of the spark plugs and place #1 wire close to a good ground ( you may have to pull the boot back a little).Turn the ignition switch on.Shift the transmission into high gear and slowly roll it forward by rotating the front wheel just until the spark occurs.Now roll it back a little.Turn the switch off.Screw the now altered spark plug and hose into #1 cylinder. You don't have to use a dying stain here.Snug will do.Next,loop and tape the hose to the radiator support rod.Pour just a little water into the open end of the hose so you have about a 4" bubble of water in the bottom of the loop.Grab the front wheel with your now greasy hands and SLOWLY roll the car forward a little at a time.Watch the bubble,it will return back to the bottom of the loop in a few seconds.The upstroke of the piston will force the bubble to the open end of the hose(BTDC) and the down stroke will draw it towards the cylinder(ATDC).Pretty simple huh? Roll the wheel forward just until the bubble decides to change direction.TDC. Done.With a little luck,George/Maine will respond with his directions on how to do the final timing.I tried it and it works great! Thank you sooo much George.
