I pulled and rebuilt the carb on my '84 Reliant but want to resolve some questions before I install it. What triggers the secondary to open in my Holley 6250? None of linkage on the driver's side seems to work it and the vacuum pull on the back only moves it a bit. Manifold side of that throttle plate was really dirty too. Even though the drivers side throttle linkage rides against a nylon roller on number 2's lever it doesn't do very much. I have attached a pic from before the cleaning. I wonder too how I can check the operation of some components before I put the assembly back on the car. There is a vacuum solenoid on the front, a mixture control solenoid on top, and a throttle solenoid on the driver's side that were only removed and reinstalled. I wouldn't recognize if they were working correctly or not. Many thanks for any input, Justin BTW, the Dodgem in Dodgem's Dad is my '85 convertible with the 2.6 that I bought new, my only new car to date.
