Are you aware that the only thing different with these is the needles (needle and seat) have springs on them for off-road bouncing around, and all the linkage is black? Bought a new one on the cheap from a member here and slapped it on a 90 W-150 318, but I ended up yanking those springs as I was having issues with fuel filling the bowls. Otherwise there are no differences other than possibly the jetting could be slightly different than the standard AVS but that usually gets changed with tuning anyway. Standard version is few sheckles less iirc.

Under or over filling the bowls ? Just curious. I may have a chance to pick up a used one.
Thanks

Under filling, due to too low fuel pressure likely, truck is a beater that I ditched the computer efi etc. I’m sure the carb is fine as designed just pitched the springs as they aren’t needed in my application. Otherwise good carb

Not sure where you get your info, but the Thunder series has an adjustable secondary Air Valve. It allows you to adjust the secondaries to come in earlier or later, with the simple twist of a screwdriver. Something a regular Performer AVS does not have the option for. This is also "Not" the off-road version. So way off with your analogy.

This is actually my go to carb in my SB cars. Easy to adjust, and just works.
Don't buy new. Look for the guy who doesn't have a clue about his new carb, and is letting it go for penny's on the dollar.

Ah **** I mistook it for the Thunder AVS 650 #1825!!! I actually have the 1826 but otherwise same carb (electric choke) Thunder AVS Carburetor #1825 650 CFM With Manual Choke, Satin Finish (Non-EGR)Which is the off road version, which I was referring too with the springs for the needle/seat/floats. Honest old deteriorating “bad eyes” confused mistake :(
