That buzz suggests it's resistance from the machine, but Tammi's pic is here and the copper strips extend toward each other from the terminals at the side and they are indeed supposed to make contact. I think your description was fine.
You can bend them or move the rheostat so they do make contact. Tammi's page is very good at explaining how it works.

Oh and if you want to check it, you can connect the two wires inside together. When you switch the machine on it will be running at full speed for sure. For those who are gasping right now, obviously this is just to test and you wouldn't leave it like that!

Cecilia,

Unless you can find a new carbon button and any of the little carbon disks you need, that foot controller is toast. It's best to just replace it. BUT --- Do not throw it away. Put it in a zip lock bag and keep it for parts. For as sure as can be if you toss it, in due time you'll need those little carbon disks for another one. That is exactly what happened to me. One controller died. Replaced it with a new one, tossed it. Not 6 months later I bought a nice cute little SEWMOR that had a damaged controller. I managed to find some carbon disks thanks to another forum member, and now it's up and running. But without them, I would have had to replace another one.

I might not have been clear about the carbon button; I actually replaced the broken one, so all was well with that part of things. But yes, I can see how it would be wise to keep one on hand for parts!

Christy and Mike, the foot controller has been futzed-with and tweaked, and I believe the sweet spot has been found.

Also I had a Smart Person check out the re-wiring and I was given an A+ for my job. ;-) Hooray, no shocks and fires here! I will run the machine and hope the snap crackle pop is indeed simply the moisture in the disks.

So, tomorrow I will put the motor back on again (it was taken off for inspection) and carefully adjust the belt. Perhaps it was too tight, causing buzzing resistance? It is a brand new V-belt, so that should be good. But I guess I have to find just the right spot for motor height.

I will also check the timing. I -think- it was okay, but I will give it a really good look in the light of day.

BY THE WAY.... the place where you drop the bobbin into (bobbin race?); should it move left to right a bit on its own, and when running machine with no bobbin or thread? I noticed this happening, and wondered if perhaps something is out of adjustment there?

Thank you again, everyone. I will be so happy when these final tweaks are done!

Cecilia S.

Okay, I am making good progress; the foot pedal is now fully in business! Also I greased and oiled the motor in just the right spots and it sounds -much- better. As well, I changed the belt to a rubber noodle belt. I know that the V-belts are said to be better, but the v-belt, although new, was causing so much resistance and buzzing and it just would not start nicely. It seemed fat and inflexible. Somehow, with this rubber noodley belt, it runs quite nicely!

Now, Mike was right; the timing is off. Following is a picture, and I would REALLY be grateful for assistance in adjusting this. I think I am just really tired and overloaded, because for some reason -nothing- is coming intuitively to me these past few days. I am also feeling a great deal of pressure, as I have promised this machine to a girl on Monday! Yikes!

Thank you in advance if you are able to help me solve the following:

p.s. Wow, that photo shows what dust has collected since I cleaned this up last autumn!!!! Must get the toothbrush out again... ;-)

Cecilia, it's identical to a 66. Someone has photographed how to do it (always better than instructions)

I'd remove the feed dog before beginning too: It'll be a lot easier to see what's happening.

Cecilia S.

Thanks Mike. I will remove the feed dog and follow those photos, as well as the TFSR link that I have from a previous timing fix on my White. I got puzzled because this is the first horizontal set-up where I have tinkered with timing and my pea-brain was just not making sense of it. But, I get that the principles are essentially the same as a vertical bobbin.

I will do this tonight and report back! :-) Thanks .

Amazing what you are doing. I hope you feel good. I feel good for you!!!

manicmike

It's funny, I was a bit perplexed first time I saw a vertical bobbin setup, but the principle is identical. The hook just looks a little different as it approaches.
Your brain seems to be working just fine to me. I've met a lot of people (men as well as women), who can't do things as simple as replacing a tap (faucet) washer or know where to put coolant in their cars. I'd think that knowing how a sewing machine works puts you at least in the top 10% of technical ability, but probably closer to the top 5%

Cecelia, It is Monday and I hope that not a pressure. I remember you said you promised this machine to a young girl today so I hope the rest of the adjustments went smoothly. If not, I am sure the young lady would rather you take some extra time with it instead of receiving the machine and having it out of adjustment.

Let us know how it went.

Cecilia S.

HOORAY!!!!!!!!!!!!!

One Monday later (due to scheduling difficulties, and thank goodness, for I needed the extra tinker time!) and the 99k has been adopted by a very sweet 12 year old girl who was just THRILLED. She loved how gorgeous and old fashioned it was, the timbre of the lamp, the feel of the machine, everything!

This is the first machine that I have re-homed, and it was such a nice feeling. Spent 1.5 hours showing her the ropes. She really got the hang of it.

I must thank everyone here, plus an offline Tinkering Guardian Angel, for all the amazing help. I have learned so much from working on this machine; and just in the past week, a lot about feed dogs, play, bobbin races, and so much more. THANK YOU!!!!!!!!!!!!!!!!!!!!

Happy happy day
