Update 2/25/2018,
As I was crossing the Golden Gate Bridge this morning a Bell Boeing V-22 Osprey flew though the towers. I love the sound of freedom in the morning.
I started this weekend by cleaning everything. I ran the case halves, fan shroud, intake manifolds, valve covers, tensioner covers, tensioner housings and oil cooler through the parts washer. The unit I used is a
Safety-Kleen AQ-1. It's a spray unit in the bottom and a sink unit on top. It's full of an aqueous cleaner called
Armakleen 4 in 1 Cleaner. It was explained to me as a combination of very mild amino acids, hot water and baking soda. Not sure that's correct so I looked it up. I verified that its safe for magnesium and aluminum and IT WORKED GREAT. I can definitely feel the baking soda in the cleaner. Everything came out looking like new. I thoroughly rinsed everything with water afterwards.
The white stuff on the outside of the case is oxidation. I'm going to media blast it.
I ran into a problem with the Webers. The throttle shafts on both units are frozen solid. They were taken off and drained 26 years ago and put into a box.
FROZEN... SOLID...
Oh and the velocity stacks are missing...
Sonoma Raceway has a couple of machine shops. One of them is Reidy's Racing Engines. I told the owner (Dodge Riedy) about the Webers and he set me up with his favorite concoction for getting things unstuck. 50/50 ATF and Acrylic Enamel Reducer. The carbs are now siting in a plastic tub in about 1.5" of this solution, enough to submerge the throttle shafts and butterflies. ATF is both a lubricant and a detergent. The reducer thins out the ATF which helps it get into tight places and eventually evaporates leaving just the ATF. Its great for getting things moving again. He uses it on old engines that are frozen. Let it soak for some time, longer the better.
The fan assembly has seen better days so its off to flyingjay to get refinished. His work is simply exceptional.
