I have a weber 38 on a rebuilt 258 w/ msd offroad6. I am experiencing hard starts (good cranking) and stalling. Thought it may have been electrical because it seemed to turn over as I was letting the key off the start position. Tried starting fluid and fired up. Rebuilt and cleaned carb, fuel filter is good. Jeep runs good as ever when it's running but dies immediately in a stall and takes 30 seconds or so to restart. Could this be an ICU issue? It's been running fine w/ this setup for three years, now all of the sudden...
