I have a 1986 Subaru GL 2 door hatchback with a 1.8L engine. Fuel pump, and filter have been replace, Carb was rebuilt a little over a year ago. Car idles and runs great when cold. As soon as it heats up, it dies. You start it back up, it runs for approx 30 seconds, then dies. Could this be a problem with the ignition module in the distributor, or is it just time for a new carb?
