Ok guys. Trying to solve a weird mystery. I had the carb rebuilt for my Daihatsu Midget what has the same motor as the Hijet. I put it all back together the same way it came apart. I took good photos before so I could make sure all the lines went where they were supposed to. Because the truck was sitting so long, I wanted to prime the fuel pump and make sure the fuel was getting to the carb, so I pulled the fuel line that went from the fuel pump to the carb. The other 2 fuel lines (fuel tank intake and return line) I left hooked up. I put the carb fuel line into a bottle so when the fuel made it that far, it would go in the bottle instead of making a mess. That's when things started getting weird. Fuel started coming into the bottle (the line that feeds the carb) as it was supposed to, so I was going to quit cranking the starter....but then all of a sudden it started sputtering and begins to idle!!!! It ran for about 5 seconds, and then died. I hooked the fuel line back to the carb and expected it to start running, but it would start anymore. Not even sputter. What the heck is going on. How is the truck running when the fuel line to the carb is disconnected?!?!?:frustration: and why won't it run now? Keep in mind this was a FRESH rebuilt carb with NO fuel in it. Am I missing something? Is there another line that goes into the carb that delivers fuel that I don't know about? HELP!!!
