What is the gap for an internal Cd magneto

[carburetor al]

I put bicycle together,Will not run.Sorry but I can not get a spark plug check while pedaling.Could my magneto be bad. Read that gap for internal CD magneto gap is closer than external CD type. Used continuity check on kill switch.It works fine.Have gas ,carb install is good.My son got it to run about 20 seconds.Could not repeat this.Does anyone know of a way to set magneto gap with internal CD.

I don't have an internal type and have never worked on one, in the old days when working on Briggs engines we would use a match book between the the flywheel and pickup, they ran pretty good.

Thanks ! I carefully moved the gap in until it was just about touching.When I rode it, popped a few times.I read on a magneto site to decrease the spark plug gap.I will try that tomorrow
