Just got a sioux valve refacer stamped model 610, no patent on it. Looks like a 620 but i can't find any info on a 610. anyone heard of one?
I'll try to remember to look at mine for a number. Mine won't take long valves on some antique motors...a real surprise and a real bummer.
If your not familiar with GOODSON, they might have some info for you as well as any consumables you might need. I have thier number if you need it.
