PD,

Thanks for the reply. One of the first thoughts was an internal vacuum leak. The plugs were not showing oil fouling but the intake was pulled and resealed anyway but showed no improvement. Three different carbs were also run on the engine. The engine runs like a champ until it warms up, no popping or backfiring. I'm planning to try the oil in the cylinders and run the compression test again.
