Weber IDA 3C Bookends? Seized Shafts Options

[mr914]

Picked up a 75 914-6 that has been sitting way too long at a body shop 8-10 years. As if I need another project like a hole in the head.

The body shop went bankrupt and the car went thru a couple of hands....

It has a laundry list of problems, including flintstone brakes, disassembled and seized webers. I picked it up for a really good price about the price of a factory oil tank.

I'll cover the car in a different tread.

The IDA3C shafts are seized on both carbs. I've pulled the carbs and manifolds to clean them up and have a few questions.

1) What is the best way to separate the manifolds from the carbs. I've removed the bolts and tried gently tapping on the manifold to break them loose.

2) Is there any hope/tricks for un-seizing the throttle shafts? Would immersion ultrasonic cleaning have any chance in freeing them?

Thanks for your input

Try tapping a razor blade in between the carb and manifold. Be careful to dig into the gasket and not the soft metals.

Ultrasonic cleaning could be a solution. Heating them in an oven could yield movement as well. A bath in PB Blaster isn't a bad idea either. I would suspect that you can be successful, but you could easily have a lot of time invested in freeing them. Take it slow and avoid any forcing.

I have been spraying them with PB Blaster for the past few days. Figured that once I get the manifolds off, I can imerse them in PB.

Have to talk the wife into using the oven.... Somehow I don't think that will be too sucessful...

Considering I bought it for donor/parts car pricing, Why would I spend big bucks on rebuilding a set of seized carbs versus taking a set of CIS injection off the shelf and converting to EFI.

If I can free the shafts, then they may be rebuildable, otherwise they will make good bookends while fiddling with the other projects.

First problem is seperating the manifolds from the carbs. Wife VETOED (IMG:style_emoticons/default/ar15.gif) the idea of using the oven. Once it gets warmer, I will fixture it up and try the heat gun.

Any tricks to seperating the manifolds from the carbs? So far Razor blade and heat


Besides, there are other problems... Yes, that is water in a cylnder head (IMG:style_emoticons/default/hissyfit.gif)

Flintstone brakes. Yes, that is a hole where the pedal cluster should be....

Nice dash though...

Getty Design. Turns out they still make them on a custom order basis.

Owner back in the 80's had a custom stereo shop so they did some funky things to the car.

Remote radar detectors in modified turn signal housing. 16 speakers, custom subwoofer in the center console.

Too bad something happened at the body shop and the car got pushed out to the back yard of the shop with no windows or doors...

Take a look on the 911 bird board. You could sell them as-is for decent money.

OK, that is a new one for me (IMG:style_emoticons/default/confused24.gif) What is the Bird Board?

[SLITS]

www.pelicanparts.com = "Bird Board" ... 911 section

How much do you want for them?

[mr914]

Ah, Pelican....

Never considered selling them. Have Linkages as well as watersheilds with K&Ns

Figured they would make great looking bookends if I cant get them functional.

Still evaluating the whole car situation, fix it, use it as a donor for another, or part it out (IMG:style_emoticons/default/sawzall-smiley.gif)

As it is still in the 20's here in Michigan, I'm fiddling with the carbs in the comfort of the basement.... Garage time is coming....

You can get a 5 gallon bucket of Mac's carb dip from your local NAPA store. Last time I got one it was around $85. It smells like mothballs soaked in methanol, but it works. I use stainless tie wire to hang the carb in the bucket, close the lid and let it sit for a day or two. You won't believe what you pull out. Never stick your hand in it. It's very caustic and will melt the blue nitrile gloves, so be careful. Never dip anything in it with plastic that you want to keep.

Go down to your local Home Depot and get a 5 gallon bucket with a lid and fill it up with diesel, drop them in and close the lid for a few days! You will be surprised how easy they come appart! (IMG:style_emoticons/default/aktion035.gif)

Diesel works really well too, but I haven't found anything that works like that carb dip.

[mr914]

What about bio-diesel?

(IMG:style_emoticons/default/agree.gif) If you're in a state that still sells it and, I believe Michigana is one of those that does, get that stuff.

Checked on the Mac's Carb Cleaner at NAPA.

Its recently been reformulated to reduce VOC's.

It's a two layer chemical, the cleaner is in the bottom of the bucket and there is a rinse floating on top.

Talked with one of the guys at the counter, the new formula does not work as well as the old version.


Its specal order and a 5 gallon pails goes for $113

[Jeffs9146]

For $16-$17 you can get 4 gallons of Diesel!
