Re: Timing problem
You disconnected the est wire I presume, and what did you time it with?

Shine it at the harmonic balancer and move the distributor accordingly

Re: Timing problem
So a timing light good. The two things you need to check are that you had the Timing light sensor connected to the right plug wire #1, and that the EST wire was disconnected. Beyond make sure to reconnect the EST wire when you're done. If it still acts up. Try disconnecting the EST wire and see if it runs ok.

Where is the EST wire located?

Re: Timing problem
Are they open? Where the engine is sucking in air through them?
