Nice work youve done!!!
First off the fuel solenoid shuts off the fuel when the key is off. you can hear it clik when u turn the key off and on. i think that it has a green wire the is in the main engine harness take a test light and make sure when u turn the key on u are getting power to the carb. Take ur line off where it goes to the carb and make sure fuel is coming all the way to the carb. make sure the ground wire to the solenoid is connected to one of the bolts on the carb. If no fire to the carb solenoid, hook a wire from the batt direct to the solenoid and see if it cliks. if it does leave it connected and try to start it. Let me know. And again. VERY NICE WORK!!!
