[QUOTE="altfuel1991, post: 182195, member: 1211"] I am in the propane conversion business and have been for twenty years. Our shop supplies kits and components for all types of engines and applications and we have many systems on rock crawlers. Are you running your vacuum lockoff on ported vacuum or manifold vacuum? If it is manifold vacuum that would explain why it cuts the engine off. It probably takes a few seconds to choke the engine down before it goes dead. At wide open throttle you have "0" manifold vacuum. Change your vacuum hose to a port on the mixer above the throttle blades and it should help. There are guys not running lockoffs but it is not advisable. If the vaporizer gets a little piece of debris in the seat it can hold it open and load the motor up when not running. If anyone needs help you can give me a call @877-403-7827 or email me bgamel@alternatefuel.com. Buddy [/QUOTE]
