the motor runs great at idle and starts every time but as soon as I throttle it runs great for 5-10 seconds. then it bogs but let off an it idles great again.
I have replaced fuel line, bought a new carb after cleaning old one was the same, Pulled out the fuel valve on the tank and cleaned out tank. I am at a loss.

Runs like perfect till throttled it dies. then wait 10 seconds and runs great again but same no mater what I have changed or done.
