How To Fix A Leaf Blower That Won’t Start?

To resolve this matter, we have discussed below the common troubleshooting problems and their potential solutions. Given below is the comprehensive home guide on how to fix a leaf blower that won’t start, have a look and access the reason why your leaf blower not starting.

 

1. Damaged Spark Plug

One big reason for this problem is a damaged spark plug. If this is the case then you would either notice a little spark or no spark at all. This could happen because of the fact that one of its electrodes is burnt. Sometimes the porcelain insulator gets cracked which gives rise to this eroded electrode. The problem also arises due to carbon fouling. In this situation, black soot starts accumulating on the plug leading to its poor functioning.

The best way to find whether the plug is functioning or not is to notice if there is a thick ashy coating gathered on the electrodes or if there is a dry or wet black sooty coating created on your plug. Another way is by using a spark plug tester. If these are the reasons why your leaf blower won’t start then the only solution is to change your spark plug and replace it with a new one.

 

2. Left Old Fuel

You might have packed away your leaf blower without removing its fuel. Normally people do not bother cleaning their fuel tanks before putting them in the shed for a complete season and as a result, leaf blower won’t start. Even if you do not clean or remove gasoline from your blower for almost 30 days, it will start deteriorating.

So after about a half year, some of the liquid will be evaporated while the remaining unused gasoline will convert into a thick dark sludge. The best way is to avoid this problem in the first place.

Always remember to remove oil from your blower before keeping it for a long time. But if you forgot to do so then first clean it properly and then add new fuel into it.

 

3. Clogged Air Filter

If your leaf blower won’t start, then it might be indicating that your air filter is clogged. There must be no obstructions in the air passageway. We all know that air is needed for ignition. This air combines with fuel under pressure within the carburetor and then produces a spark. Since a leaf blower forces air out of the nozzle to blow debris and fallen leaves, simultaneously the other end of blower acts as a good vacuum for flies insects and other dust particles.

So the whole opening gets clogged leading to insufficient air supply. To prevent this problem, always check your air filter, clean it with lukewarm water and soap. If it is too dirty to clean then you may have to replace it.

 

4. Rewind Spring

When you pull your rewind string, it goes back into the pulley and the blower is started. But if your rewind string is broken it won’t go back to its place when pulled and hence your leaf blower won’t start.

This problem can be resolved by replacing the old broken string rewind with a new one. If you do not know how to do it at home, then take it to your mechanic and get rid of this problem.

 

5. Poor Compression

Still, finding the cause of leaf blower not starting? The next possible reason could be poor or low compression due to an untightened or loose spark plug. This will cause air to enter or leave the combustion chamber and hence leading to poor mixing of both fuel and air. Other common reasons include broken valves and a damaged head gasket.

As a solution first try to tighten the spark plug. If it is already fine then do not over tighten it as it can cause severe damages to both the engine and the spark plug. Repairing broken valves and head gaskets require high skills. So do not take risks if you do not know how to fix it.

 

6. Fuel Filter

A fuel filter needs to be replaced every few months. This is because blockage in the fuel filter will prevent your leaf blower from starting. Also, it will decrease the life of the fuel pump. Usage for a long time will allow dirt to enter the fuel filter and causes obstructions.

In order to get rid of this problem, you can either take it out to clean it or replace it with a new one. If you are cleaning it at home, always remember to remove fuel first and then clean the fuel filter and fuel lines properly.

Conclusion

Once you have found the reason why your leaf blower won’t start, you can easily implement these above solutions to eliminate this problem at home. If the problem persists then it’s better to contact the company’s customer service center. Also, if you do not know how to repair the broken and faulty parts of your leaf blower then you should seek some professional advice or take it to the mechanic to avoid further damage.

However, these solutions might not help if your leaf blower is quite old or you have used enough of it. It is difficult to figure out the problem if the engine is faulty. In that case, you cannot simply repair it at home. Always put your leaf blower at a safe place and remember to clean its parts regularly. If you do not use the device frequently or use it after a long time then it’s better to remove its fuel before keeping it.
