My 931 starts up fine but after I let it idle for a couple of minutes it starts to sputter and die. It will restart but not maintain idle.

If I have to adjust anything could you please picture the engine and point out the places to increase or decrease.

Thanks a bunch.
Vince

My first guess would be that you've got a vacuum leak somewhere.
Extra richness provided by the CSV and WUR at cold startup can be keeping it running at the beginning, but once it's leaned down to the running mix, a vacuum leak can leave it too lean to idle..
