Power Technologies 10 Big Ideas

  • Mechanical service begins with operator safety
  • Social, ethical, and sustainability considerations impact design
  • Complex tasks require the sequencing of skills

This year we have will be fully rebuilding 4-stroke and 2-stroke engines, then will tackle a mix of inquiry projects lead by the students. Check back often for our progress!

4-Stroke Engine Rebuild Troubleshooting

Compression Test

Compression under 100psi;

Do a dry then wet compression test

Check your Valve Adjustment

Check for leaking gaskets with the smoke/leak detector

Check Crank-shaft and Cam-shaft timing marks

Spark Test

No spark;

Test spark plug

Test spark plug wire and ignition coil

Check if ignition coil to flywheel spacing is 0.010″

Test kill switch circuit.

Fuel Test

WARNING: Gasoline is HIGHLY explosive. Check with the teacher before continuing

No fuel getting to engine; Check for gas

Check the fuel shut-off valve

Check the carburetor for clogged ports or jets

Check the needle and seat for damage.

Congratulations Everyone! The 4-stroke engines are coming along nicely. Amazing trouble-shooting shown by everyone.

Remember before you start your engine to check for compression and for spark. This will eliminate most of your no-start issues.
