Can anyone tell me the jet size for part #404 945 R91? Carb is 405 004 R91 (I think). Need to find out to fix Stanton's carb tomorrow at the Kansas Cubfest. I can't find it anywhere I've looked.

Thanks, Bob

I found the number .040 in an I&T repair manual. Haven't seen anything to contradict it.

With that size main, I'd bet the venturi is the larger one. Hope the discharge nozzle matches everything, I'm having a heckuva time getting mine to all match up :(
