GX-120 and GX-160 Instructions

GX-25 Instructions

Week 1:

• Get one toolbox and one engine from your lab AI.
• Disassemble the engine completely following the directions above for your specific engine. As you disassemble, remember that you will need to put it back together again AND the engine needs to start when assembled. So you can't lose nuts or bolts in the process.
• Take a group photo with the completely disassembled engine; this serves as documentation that you completed the disassembly.
• Complete the Worksheet questions under "I. Post-Disassembly" before putting the engine back together.

Week 2:

• Reassemble your engine. When you're done, call Mike over and we will start the engine and see how you did! If it doesn't start, you will need to troubleshoot till it starts.
• Complete the Worksheet questions under "II. Post-Reassembly"
