Re: 80 kitty cat doesn't idle - help
A snowmobile carburetor that won't idle could be due to various issues, and clogged jets are indeed one of the potential causes. Here are some steps you can take to troubleshoot the problem:
- Check the Fuel: Ensure that you have fresh, clean fuel in the snowmobile's fuel tank. Stale or contaminated fuel can lead to carburetor issues. Drain any old fuel and replace it with fresh gasoline.
- Inspect the Air Filter: A dirty or clogged air filter can affect the air-to-fuel ratio and cause problems with idling. Remove the air filter and clean or replace it if necessary.
- Clean the Carburetor: If you suspect the jets are clogged, it may be necessary to clean the carburetor. Start by removing the carburetor from the snowmobile according to the manufacturer's instructions. Carefully disassemble the carburetor, taking note of the jet locations.
- Clean the Jets: Use a carburetor cleaner and a small, soft brush to clean the jets. Pay particular attention to the idle circuit jets, as these are most likely to cause idling issues. Ensure that all passages and orifices are clear of any debris or residue.
- Reassemble and Adjust: Once the jets and carburetor are clean, reassemble them in the reverse order of disassembly. Make sure all connections and seals are secure. Refer to the snowmobile's manual for any specific adjustment procedures, such as idle speed or mixture adjustments.
- Test and Fine-tune: Start the snowmobile and allow it to warm up. Test the idling performance, making note of any improvements or continued issues. Fine-tune the carburetor adjustments if needed, following the manufacturer's recommendations.
