Done so far: rebuild carbs, installed new plugs, coils and fuel pump. all new internal hoses and prime ball. New clean non-e fuel. Carb bowls are full. Strong spark. Compression 122 all. Can hold hand in front of carbs 2 and 3 with no effect but suction is strong. Hand in front of carb 1 shuts down engine. Chocking has no effect. Starting fluid in carbs 2 and 3 by-passing carbs has no effect. All old plugs indicate slightly rich mixture but in normal range. Idle jets set at one and one half turns out. Flywheel timing good. Spark advance good. Any suggestions?
