Hey Guys I've been shakin' down my 'A' with only the primary carb of the tri-power fed. The other day I plumbed the secondaries. Here's my quandry..these guys are weeping fuel. I lowered the fuel level,but am still experiencing load-up. The secondaries are the real deal..not just another set of 2GC's. Would a minute leak past the throttle plates cause vacuum to "pull" fuel through the venturies? I do not believe I have any vacuum leaks as I get good metering through the idle /air adjustments on the primary carb and as soon as you monkey with the secondary throttle plates(vacuum leak) the engine dies. Any help greatly appreciated!!
