Surged to the point of stalling. I ended up spraying carb cleaner at the point where the intake met up to the head and found when spraying the carb lceaner at the no 1 cylinder, the engine speed noticibaly changed. The Intake gasket was replaced and the issue was resolved.
Rough idle, stalling, idled fine if you kept foot on gas. Intake gasket was blown out. Replaced gasket. All is well
