Pull-starting a Yamaha Big Bear ATV can be a bit of a workout, especially if the engine hasn’t been run in a while, but there are a few techniques that can make the process smoother and more reliable — regardless of the exact model year.
First, make sure your choke is engaged if you're starting cold. Most Yamaha Big Bear models, especially carbureted ones from the late '80s through early 2000s, require a properly set choke for a cold start. Turning the fuel petcock to the ON or RES (reserve) position is also essential if it’s been left OFF.
Before pulling, verify that the kill switch is set to RUN and the key is in the ON position (if applicable). Also check that the transmission is in NEUTRAL — some models have a safety interlock that prevents ignition unless it’s out of gear.
Once everything is set, give a few slow primer pulls to cycle fuel through the carburetor. Then, perform a strong, steady pull. It often takes 3–5 good pulls if everything is working properly. If it’s been sitting for a while or the carburetor isn’t clean, you might need to prime more fuel manually by gently opening the throttle while pulling — but avoid flooding the engine.
If you're struggling to get it started, spark plug condition and carburetor cleanliness are usually the top culprits. A weak or fouled plug can cause hard starts, as can a gummed-up pilot jet. Keeping your battery healthy (even for electric-start backup) and the air filter clean will also go a long way in ensuring easy starts, even when using the pull rope.
In short, the key steps are:
- Choke ON (for cold start)
- Fuel valve set to ON or RES
- Transmission in NEUTRAL
- Kill switch and ignition ON
- Use smooth, firm pulls — not quick jerks
If it still won’t start, checking spark, fuel flow, and compression would be the next logical steps. Some Big Bear owners also find that replacing old recoil springs or lubing the pull starter can reduce effort.
These are tough machines, and once tuned properly, they usually start without much fuss — even by pull-start. If you're dealing with persistent starting issues, a good cleaning of the carb and ignition system often brings things back to life.
I hope it helps!
