steelmesh Posted March 11, 2020 Share Posted March 11, 2020 I am building a paramotor using the Top 80 with the WG8. I have a universal frame that came with a gas tank ready for drilling. After some deeper research into specifying what I need I have learned the black springs steel on the carb is for priming, "priming level". Based on my knowledge of similar carbs the priming lever will manually open the needle valve. Just clarifying my understanding here, by pressurizing the fuel tank and then hitting the priming level, that would squirt fuel into the carb throat. Is this a correct statement? If that is the case, I think I understand how the priming bulb will work with this carb...because before I was concerned that the primer bulb inline with the main fuel feed to the carb would need to exceed pop-off pressure to force fuel through the carb. So it appears that you build a little pressure with the inline primer bulb and then hit the manual primer lever. I was looking at putting in an independent primer system (it's own fuel pick up and a nozzle inside the carb or airbox); until I started finding Top 80 youtube videos trying to trace their fuel lines haha, that's when I saw the primer bulb inline.
