Timing without disconnecting EST?
Anyone know what the timing should be on a '90 IROC with the 350 TPI at idle when warm WITHOUT disconnecting the EST? I just want to see if the ignition module is operating properly after I rebuild the distributor. Thanks guys.

Do you mean without disconnecting the bypass wire? If so, it usually runs in the 20's.

Thanks, Tim. Yeah, I just wanted to check and see if my advance system was working OK. The base timing looks good but I think it's at about 30BTDC with the EST bypass connected. I plan on rebuilding that distributor this week so we'll se if that helps.
