My engine's choking
If the fuel tank vent is blocked, the engine chokes because it cannot suck in fuel. To check this, open the filler neck. If the engine starts again, the vent was blocked.
My motor's not running properly
It's probably an injector defect. Loosen and tighten them one by one to find out which one it is. The one that needs to be changed is the one that doesn't change the engine speed.
My engine vibrates or knocks
- Alignment problem or silent block, motor may be misaligned or propeller shaft twisted.

My engine smokes blue
