About the only thing you will find with a carb that will work with out an accelerator pumps a chain saw. You rev them up to speed at almost no load and go to work, unlike a vehicle that has to do a lot of work to accelerate you up to speed.
Another way you can run with out an accelerator pump is to run your carb catastrophically rich.

Years ago I set my Camaro to run a lean idle after I installed a wide band O2 gauge. One day I was changing out accelerator pump jets and forgot to reattach it to the linkage. I started the car, put it in drive and as soon as I touched the gas it died and I figured I forgot to reattach the accelerator pump more or less immediately.
Now a few years before that, I was messing with that car, when it was running really rich before I had a wide band O2 gauge and deluxe carb tuning set and disconnected the accelerator pump to see if it would go and it kind of did. But it was more or less undriveable with no accelerator pump.
