Predator 212 Won't Start: Full Diagnosis
Predator 212 · 8 min
A Predator 212 that won't start almost always comes down to one of three things: fuel, spark, or air. This guide walks you through each in order so you find the problem fast.
What you'll need
- Spark plug wrench
- Carb cleaner
- Small flathead screwdriver
- Clean rag
Steps
Check the basics first
Make sure the fuel valve is ON, the choke is closed for a cold start, and there's fresh gas in the tank. Old gas that's been sitting more than 30 days is the #1 cause of no-starts.
Test for spark
Pull the spark plug, reconnect it to the plug wire, and hold the threads against the metal head while pulling the cord. You should see a blue spark. No spark means a bad plug or coil gap.
Inspect the spark plug
A wet plug means too much fuel (flooded). A dry plug means no fuel is reaching the cylinder. A black sooty plug means it's running rich. Clean or replace as needed.
Check fuel flow
Remove the carburetor bowl (the bolt on the bottom). It should have clean gas in it. If it's empty or full of varnish, the fuel line is clogged or the carb needs cleaning.
Clean the carburetor
Spray carb cleaner through the jets and passages. The main jet in the center of the bowl nut is the most common clog. Clear it with a thin wire and blow it out.
Reassemble and test
Put it back together, set the choke, and pull. If it fires and dies, your idle circuit is still partially clogged — repeat the carb clean.
Mechanic's tip
If it ran fine last season and won't start now, it's the carb 95% of the time. Drain the old fuel before anything else.
