Hey Glenn70,
Starts, and runs, upon application of throttle engine hesitates and stumbles.
Have a MSD ready-to-run distributor.
I reset timing and set a 6* BTDC, she's idling great, but in gear get a mean viberation / shake.
Im leaning toward valves too tight.
Shaun P: I utilised the degree wheel to make sure that I was only turning the engine the correct 1/4 turn each time to set the valve lash, as my balancer lacks any markings, other than the factory one's.
Sorry if this is a high jack, thought it sounded similar to my issue.
