A little background on these....
I bought a ‘82 320IS for the 5spd swap and other goodies. The car had been sitting for 2+ years and with a full tank of fuel. I drained all the fuel and put fresh fuel in and for the life of me I couldn’t get the car to run without using quick start.
Came to the conclusion the carbs needed to be rebuilt and I wanted to hear the M10 run. So, I dropped them off at a carb shop and had them rebuilt. They ordered complete rebuild kits, ultrasonic cleaned them and media blasted them with plastic bead.
Once done, I mounted them on the car and with in 30secs of cranking the car fired up. I took the car for a blast up the road and put it back in the shop. Put a 1/2 can of sea foam in the fuel and ran the car for 5 mins and then drained the fuel from the carbs and started the car to run them dry.
The one stack tack is butchered as the booster was in the way. I would buy a shorter one or ones from IE that upsweep to replace it.
Now they can be yours for $400 USD + shipping.
