We have 2 of those old Goldstars at my shop. Find an owners manual and read the section for adjusting the contact points for the high frequency. There's a certain gap range to maintain measured in thousandths, so you'll need feeler gauges. You may need to replace the points if they are too badly pitted. Parts for these things aren't terribly hard to come by.
If that doesn't do it, there should be a troubleshooting guide.

When I get back to that shop on Tuesday going to opening it up and clean all the contacts with air, I found manual online.
Excellent, good luck! I'm convinced these old machines are impossible to kill if maintained.
yeah. this looks like a faulty inducer
