Re: EB Timing problem help urgent
Ok to get TDC:
a) take all the spark plugs out.
b) Rotate engine by hand (clockwise) .
c) Put thumb over # 1 plug hole so you can feel compression stroke; rotate several time so you get the feel of the the difference between compression (pressure on thumb) and no-compression/exhaust (sucks thumb) upward stroke of # 1 piston.
d) On end of upward compression stroke timing marks of crankshaft pulley should align with TDC mark on timing cover.
e) Now replace distributor so rotor points to number plug lead on cap (setting mark of distributor internal cover) and the TFI module is at about 60 degrees to a vertical line running through length of car (i.e 60 degrees to side of rocker cover).
f) Note apply an engine assembly lube to distributor drive teeth before putting it in.
g) Note distributor will move sightly when you put it in so start at a different angle so it ends up at 60 degrees. Some internal covers have a start mark that makes this bit easy.
h) Setbase timing. Run engine until warm,turn A/c etc off, attach timing light, set diagnostic function (have you a code reader if not ground self test input with a jumper) . Self test mode will set revs to 1300/1600 (so attach a tacho). Ajust timing as normal (10 degrees BTDC).
