Summary

Singer Heavy Duty 3.5mm gauge

This is needed to put your timing into spec (owner manual concerning fixing the timing is attached to this thing)

It's just a stupid simple 3.5mm block.

Print so its fairly rigid, and I recommend ironing. Just use calipers to ensure it's 3.5mm so sand/lap if need be! If you need an easy way to lap parts check this video out!!-- https://www.youtube.com/watch?v=uO2QHQSSpwE

Hope this helps!
