and it was fine before you adjusted the timing ? what did you set the timing at with the connector unplugged ? when it will not start what is the engine doing ?poping?acting liek the starter cant turn the engine over?
Customer: replied 2 years ago.
after putting a new disributor in i set the timing at top dead center. hooked up the timing wire and it will start and die. unhook the wire and it will run good.
Expert:  Gary replied 2 years ago.
and it did NOT do this with the old distibuter ? and you are sure you have the timing light on the # 1 wire and what did you set the timing spec too on the timing plate? 0 degrees?
Customer: replied 2 years ago.
i replaced the distibutor because it need a pick up and module so i replaced it with a NEW distibutor. my light was on the #1 wire and set at 0 degrees. If its cold it will start with the computer hook till it warms up, then it starts jurking and dies. i disconnect the wire and it will start up and run fine. I did replace the computer but didn't help.
Expert:  Gary replied 2 years ago.
if that timing is set at 0 and when you hook that timing connector up( C114 in this picture ) and it dies but will be fine with it unhooked and it did NOT do this with the old distibuter there has to be something wrong with that distibuter

Let me re read what has already transpired here. I'll be right back
Customer: replied 2 years ago.
thank you
Expert:  Dad Mechanic replied 2 years ago.
can you retrieve your old distributer? I assume you didn't check your timing before you changed your distributer? Have you verified that your timing marks are correct on the damper, the outside has been known to become un vulcanized and slip. Have you tried to just set the timing by ear. I would try to set with the wire off at 12 degrees advance and hook the wire up and see what happens. If this helps you could have a damper problem.
Customer: replied 2 years ago.

the timing marks are correct. I tried ti advance it to 8 degrees and that won't work so i guess i will try 12???

Expert:  Dad Mechanic replied 2 years ago.
If you want to check for 0 degrees on the damper you can remove number one spark plug and put screw driver in the plug hole and turn the motor over by hand when it stops mark the damper at the pointer now turn it in the opposite direction until it stops mark the damper at the pointer 1/2 way between the 2 marks 0 should the there. jim

-i ment a trial at 12 advance if that seems to not work try 12 retarded. i think you should get it to run with the wire hooked up and set the timing by ear use to do to set timing this way all the time.
