I'm not sure why on a street car anyone would tell you to lock it out. now making sure your fully advanced timing is right....thats worth looking into.
What is the rest of the combo? How does it get driven? What RPM does it idle? Do you know what your total timing is?
Since you are asking, locked out timing means that your car will start and idle at your total advance number whatever that is, probably 32-36 degrees BTDC. If it's hard to start at 22, no way you want to advance it more.
Drag cars usually leave the line at an RPM somewhere above or close to where timing stops advancing. WOT performance would suffer with anything less than full advance. On the other hand, any car that spends time operating at part throttle benefits from an advance curve.
