I have a Kodiak 400 that idles fine but bogs or dies at any throttle. I have - Drained and replaced gasoline. Replaced fuel valve due to the screens being cracked. I have put all new jets in the carb. I have cleaned the carb 3 times, the last time i soaked and blew it out with an air tank. I have replaced air filter and the spark plug. I have also replaced the throttle valve because i broke part of the original one. I am at my wits end. If i hold my hand 50% over the air intake, it will rev fine. Please help and tell me what i am missing here.
