[QUOTE="TacomaJD, post: 437152, member: 1780"] [b]Re:[/b] The only way fuel gets to the carb/intake is via vacuum, so it seems it would have to be vacuum related. The vaporizer has a diaphragm and other parts that could be factors, but unless something is restricting fuel flow, pushing the button opens the diaphragm and allows fuel to pass through it and onto the carb. Propane systems are quite simple when it comes to it not running at all. There can only be a couple things wrong. If the throttlebody, intake, and hoses do not have leakes, it sounds like the diaphragm in the mixer. Mixers are pretty simple. Make sure the lean/rich valve is set about in the middle while troubleshooting, then you can fine tune it later when it's running.
