Removing frozen parts can be challenging, but with patience and the right approach, you can increase your chances of success without causing damage. Here are some steps and techniques to help you remove frozen or rusted carb parts:

1. Safety First:
   • Always wear safety goggles to protect your eyes from flying debris or chemicals.
   • Use gloves to protect your hands.
2. Tap Lightly:
   • Lightly tap the head of the bolt with a hammer. This can help break up some of the rust or corrosion binding the bolt.
3. Apply Penetrating Oil:
   • Spray or apply a penetrating oil (like WD-40, PB Blaster, or Liquid Wrench) onto the bolt.
   • Let it soak for several hours or even overnight. This helps to dissolve or loosen the rust and corrosion.
4. Apply Heat:
   • Use a propane torch to apply heat to the bolt for about a minute or two. This can cause the metal to expand and then contract as it cools, which may help break the bond. If possible heat around the outside. The outside metal will expand allowing the bolt to be remove.
   • Remember to be cautious when using open flames, especially near flammable materials.
5. Use the Right Tools:
   • Use a six-point socket or wrench. This gives better grip and reduces the chance of stripping the bolt head.
   • Consider using a breaker bar for added leverage.
6. Impact Tools:
   • An impact wrench or impact driver can be very effective. The rapid hammering action can break the bolt free.
   • If you don’t have an impact tool, a manual impact driver (which you strike with a hammer) can also be useful.
7. Left-Handed Drill Bits and Easy Outs:
   • If the bolt head strips or breaks off, you can drill into the bolt with a left-handed drill bit, which might cause the bolt to turn and unscrew while drilling.
   • If that doesn't work, you can use the hole you drilled to insert an easy out (or screw extractor) to grip and turn the bolt out.
8. Heat and Wax or Candle:
   • Heat the bolt as mentioned earlier, but then press a candle or paraffin wax against the heated bolt or surrounding area. The heat will draw the wax into the threads, which can lubricate and make it easier to unscrew.
9. Nut and Welding Technique:
   • If the bolt head is broken off, you can weld a nut onto the remainder of the bolt. Once it cools, you can use a wrench to turn the welded nut and hopefully the bolt as well.
10. Inspect and Prepare for Reassembly:

• Once the bolt is out, clean the threads in the hole (a tap set is ideal for this) and on the bolt (if you intend to reuse it, though it's often better to replace it).
• Use anti-seize compound when reassembling to prevent future issues.

Remember, patience is crucial. If one method doesn’t work, try another. Forcefully attempting to turn a frozen bolt without any of these techniques can result in a stripped or broken bolt, making removal even more difficult.
