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.

send the whole lot to Mike Pierce at Pierce Manifolds in Gilroy, CA

- he will completely re-do them to perfection

if ya have to ask the price, ya can't afford the car

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)

ah! i missed the most significant info - a 1975 914-6

it's a conversion - worth whatever you can get for the parts

in that case - just sell the webers - eBay is good

- junk webers go for 600-800 all the time
