Where can I buy spark plugs for a snowmobile

Sooner or later, the ignition system element stops working, it has to be changed. When you need to do this, refer to the passport in which there is a recommended mileage, after which a replacement is necessary. But the component does not always work up to the specified dates.

There may be several reasons for this:

• low-quality fuel;
• inappropriate candles;
• faulty voltage wires.

How to understand that you need to change or clean the spare part without the use of instruments and diagnostics:

1. Intermittent engine operation.
2. Loss of power and dynamics of the snowmobile.
3. High fuel consumption.
4. Deterioration in launch.

If you have problems, then it’s time to change the product. On the website of the online store you can easily find it by first entering the article of the candle in the search bar.

How to remove carbon deposits from candles

After the purchase, over time, you will have to perform diagnostics, check the spare part for carbon deposits. Also, if the engine is deteriorating, the following operations must be performed:

1. To clear a deposit an ordinary sliver from a tree which is moistened with gasoline (or acetone). It is possible to heat parts of the thermal cone to 400 ° C.
2. Using a directional flame, heat only the portion adjacent to the gap. But use the heating method carefully, because the parts are sealed with a material that is a dangerous glass sealant.
3. It is undesirable to use metal brushes to remove carbon deposits because there are risks of “enveloping” metal elements on the ceramic surface, which contribute to the occurrence of electronic “breakdown” of the candle;
4. Adjust the spark gap and center the outer electrode relative to the center by gradually bending the first one.

Now remove the soot and other contaminants from the outside of the insulator. Check the performance of the spare part: the spark should “slip through” on two cylinders.
