You peen the screws so they will not fall out and become ingested by the engine. When you peen them you use a center punch, but make certain that you support the shaft from the oposite side so you don't bend the shaft. Lock-tite is a good idea too. I'd use "blue". So you can take it apart, if necessary.

Yes, I've seen many carbs run fine after all that removal and reinstall.

Also, as I said earlier. Mark where the plates go before you remove them. When you put them back in the bores and through the shafts, you should leave the screws slightly loose so you can fit the throttle plates to the bores so they are centered and don't stick to the bores. Hold them up to the light and see the light around the edges to help in centering them.

Lastly.....don't use "Force" on anything in the carb. You'll have trouble later for sure. Let them soak for some time, like overnight.

Take care...
Merry Christmas !!!!!
