Recently acquired this machine.
When it starts and runs it runs well at wide open but struggles to idle properly.
When the LP bottle is turned on i can hear gas flowing through the throttle body when the key is on. If i shut the LP off and attempt to start it i can get it to crank with the bottle slightly cracked.
It seems the machine is flooding.
I have been able to retrieve codes.

Any help is greatly appreciated.
