I finally got around to switching out my tired Holley 2 barrel to a rebuilt (by me) thermoquad. It fired right up and runs great, performed an idle mixture adjustment and it’s smooth as silk. No bog, no hesitation and I couldn’t be happier. My problem is when I went WOT for the first time one of the metering rods fell out, they aren’t really retained by anything they just move around in the hole in the plunger saddle. Is this a common problem? Anybody know what the fix is? It only did it once, subsequent WOT operations went fine. I know this will happen again. Any ideas guys?
