I have a tvt691 with arc rods and flywheel, isky cam, ported heads 5/16 valves ecdual springs and retainers. 17.5 hp carbs with blue tubes and brown jets. .026 lowsde. Now it cuts out opening to wide open throttle without the breather. When I put the breather on it won't open at all just stutters. I opened the small side of the brown jets to .039. Timing is set at 34*. Cam is 270* .400 lift. Heads or cam maybe too big? Keeps fouling plugs maybe high side too big. Help please it's kicking my :censored:
