My 17 year old son and I have about 9 months into this project. Our first car, working together. Real 'encounter session'. We have the car running with many learning-experiences along the way.

1. Brake Cylinder - weird installation method, on our 3rd re-try, when will it stop leaking?
2. Valve adjustment - third time was a charm - man can this thing make noise!
3. Pedal assem - Seems OK.......then: let's take it apart and make it smoother.
4. Transmission linkage - All seems in Order, what are those bushings??? Hhhm, rebuild
5. Throttle Control - seems sticky, let's rebuild it! 911Rubber!

Pretty rough looking after 45+ years

I would like to add that I am trying to figure out the best method to clean parts. Currently we are using degreaser and then various wire brushes (steel and synth) which is less than optimum. Comments welcome!

Larger and correct orientation of the pictures can be seen by clicking on the top right of the photos that seem to be turned on their side - could not get this 'feature' to stop working.

How was the shaft inside the TB? They have a tendency to wear and wobble a little, and then you do not get a reliable, consistent closed throttle position. The fix is to bore it out slightly and insert bushings.

Glad you're having fun with your son (IMG:style_emoticons/default/smile.gif)

I have used wire brushes on a Dremel type tool. It is that time of year again folks for me to say those wire brushes can spray out high speed wire arrows. I know one of them added a piercing to my nose. Had it been my eye... but I was wearing goggles. I know that you would have been wearing them too. We all go to such great lengths to roll back the clock on the toy cars of yesteryear. Good for us, but be safe out there.

I use pinesol great on the aluminum , but don't use it on the brass it doesn't hurt it but turns it black, also pinesol will strip cad plating.

FYI, in regards to cleaning options; I just cleaned my 30 year
old S&S carb in my ultrasonic cleaner, submerged in a 1:1 solution
of simple green “HD” and water.
After only 1hr at 60C the parts look like NEW!

I bought following model, which has served me well the past two years:

VEVOR Commercial Ultrasonic Cleaner 6L

https://www.amazon.com/dp/B01HGNYO0U/ref=cm...i_RbdQCb5V7Z3RM

Also, the six liter tank is big enough to clean even most of our 901 transmission parts.
Bigger is better, but it will require also more cleaning solution for the same part.
