I picked up a .61 SF ABC that appeared to be in pretty good shape. It was sitting on a shelf in someone's basement for years.
Here's my problem.

The engine won't idle. It looks like it isn't pulling fuel below half throttle. If I open the throttle wide and prime the engine, it
starts on the second flip at 1/8th throttle. It runs for 10 seconds and dies. I pulled the 7L carb and carefully disassembled it on the bench, looking for dirt or other problems. Nothing noted. One thing bothers me. The opening in the spray bar doesn't look right. If you look at it through the bottom, there isn'y much of an opening and the shutter it rotates in is covering half of the fuel opening. I have very little experience with this old motor and I need help. A new carb is more that I paid for the engine.
