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 |

Went out to the local watering hole (IMG:style_emoticons/default/beer3.gif) and thought about the issue. 1 - if it is loctite that is holding the manifolds up, Depending on if it is Blue, Red or Green... each has a release temperature. Blue is about 160F and green is in the 230 range. It's finally warm here today... 50 for the first time in months.... Headed into the garage and broke out the heat gun and warmed up the manifolds/carbs. Gave it a ketchup bottle thump (IMG:style_emoticons/default/smash.gif) and the manifold separated! Tried the shaft and the butterflys are free. Even with the helper spring removed, i could go to WFO and it would snap back to position!! Time for the second carb. Same process, heat up with the heat gun. Thump the manifold and it came free. This time a little different story, more corrosion on the shafts. 3/4 open, the butterfly’s will snap back but not from WFO. One of the butterflys is pretty corroded. The others cleaned up fairly well with carb cleaner and a toothbrush. Appears that it was a bit of carbon that was holding them up Still going to soak them and see what can be cleaned up. Now to find some manifold to carb gaskets..... Anybody have a set? Attached image(s) |
