Yes, but it will not be pre-mixed with air. It will idle rich.

Tip in is
1. Idle circuit. If this is fine at idle, this is not the cause.
2. Transfer port. This is checked by holding the throttle open slightly (idle + 200 RPM) to see if it's lean there. Most 70s-up stock carbs are a bit lean here.
3. Accelerator circuit. This will show up at any RPM, but be more noticable at low RPM. Do you have issues at say 30 MPH?
4. Main circuit. This should start to work at ~1400 RPM. You can see this by looking down the throat. WARNING! lean pop may catch you in the face!
5. Power circuit. When it's a quick tip in, the vacuum drops enough to open the power circuit. If it is needed but does not work, this will also be a flat spot.
