What should the compression reading be on a leaf blower?
An ideal compression reading would range between 90 and 110 psi for a cold leaf blower. If your leaf blower shows a compression reading of less than 90psi, then it is an indicator that your leaf blower has a compression leak and does not produce optimal compression.
What size engine do I need for a leaf blower?
Leaf blowers use 2 stroke engines ranging between 30 to 50 cc. While the minimum compression a 2 stroke engine needs to complete the combustion process is 90 psi, you cannot expect a leaf blower with such a low compression reading to produce much power.
Do leaf blower engines lose compression?
Leaf blower engines, just like any other engine, are pressurized, and the engine should maintain a certain level of compression to run properly. Not having sufficient compression can make the job inefficient and tedious. As long as your leaf blower’s engine is optimal and you perform regular maintenance, your leaf blower shouldn’t lose compression.
What is the best CFM leaf blower?
The Ryobi RY38BP is another high CFM leaf blower option at 760 CFM. It’s not quite as powerful as the RedMax, but it’s still powerful enough to tackle large yards and mountains of leaves. It’s a fantastic budget-friendly leaf blower at less than half the cost of the RedMax, but the tradeoff is that the brand isn’t as well-known.

0:001:38Now I do all my compression tests with the engine cold. So I'll just start by removing a spark. PlugMoreNow I do all my compression tests with the engine cold. So I'll just start by removing a spark. Plug. Now going to insert the compression tester in there.
What is normal cylinder compression?
“Good” compression depends on the engine. Unfortunately, engines don't come with their proper compression stamped on the outside. But a good rule of thumb says that each cylinder in a mechanically sound engine should have compression of 130 psi or higher.
What is normal compression for a lawn mower engine?
Typically most small engines, for lawn mowers, will operate within a range of 80 PSI (pounds per square inch) and up to 140 PSI. This range will depend on horsepower size of the engine. A reading below 80 PSI generally indicates there is an internal leak to the combustion chamber and it must be repaired.
How much compression should a 2 cycle engine have?
Pull the starter rope a few times to get an accurate compression reading. Normal compression is between 90 and 110 psi.
How much compression should a Craftsman leaf blower have?
A leaf blower engine should have at least 90 to 100 psi of compression.
Why is my Stihl blower not blowing hard?
Common causes of leaf blowers not blowing hard include clogged carburetors, flooded engines, using old fuel, damaged spark plugs, or clogged fuel filters. Solutions include cleaning the carburetor, draining the engine, using fresh fuel, replacing the spark plugs, and cleaning the fuel filters.
What can cause a motor to lose compression?
What Causes Loss of Compression in an Engine?Holes in the Piston. ... Leaking Valves. ... Blown Head Gaskets. ... Glazed or Splintered Cylinder Walls. ... Weakened Timing Belt or Cracked Chain. ... Worn Piston Rings. ... Damaged Valve Springs, Seats and Retainers. ... Worn Out Camshaft.
How do you check compression in a small engine?
Insert the hose of the compression gauge into the empty spark plug hole. Pull on the starter cord 10 to 15 times, or until the compression gauge needle hits its maximum level. Compression should reach at least 90 PSI if it's hot, and at least 100 PSI if it's cold.
How do you test a blower coil?
To test the ignition coil on a leaf blower you should follow these steps:Open the motor.Detach the parts.Disconnect the wire that runs to the spark plug.Remove the ignition coil.Test with an ohmmeter or a multimeter.Start the test.interpret your observation.Decide what the fix will be.More items...
How many CFM can a leaf blower blow?
You can purchase leaf blowers that range from 200 to 1000 CFM, and sometimes even more. If you are considering purchasing a new leaf blower, think about the size of your yard, the price you’re willing to pay, and the other features that are important to you before deciding which one is the best solution for you.
How much CFM does an electric leaf blower blow?
You can get away with between 200 and 400 CFM if you just need to clear a few leaves or grass clippings away every now and then. If you own at least an acre, though, ...
What does a higher CFM mean?
A higher number CFM means the leaf blower will have more power to move things. Some leaf blowers have very high CFM ratings. For instance, a leaf blower CFM of more than 500 will have the power to move large piles of leaves and possibly even sticks or small rocks. A leaf blower CFM of more than 800 will have the potential to blow small rocks ...
What does CFM mean in leaf blower?
CFM is a measurement of volume. It stands for cubic feet per minute. Leaf blower CFM refers to how many cubic feet of air come out of the blower’s nozzle every minute. In other words, this is the amount (volume) of air being pushed through the end of the leaf blower. For example, a 500 CFM leaf blower moves 500 cubic feet ...
What does CFM mean in air?
CFM has more to do with power than speed. MPH stands for miles per hour and it refers to how quickly the air is moving when it comes out of the nozzle. Fast moving air tends to be stronger than slow moving air, but that’s not always the case, and it’s not a direct correlation.
Is a leaf blower stronger than a low MPH?
Purchasing a leaf blower with a high MPH rating doesn’t always mean its stronger. Even a low MPH leaf blower will be very strong and have a lot of power if the CFM specification is high. Generally speaking, if you want to move more leaves, look for a higher CFM, not a higher MPH. A higher CFM rating typically comes from a larger, heavier motor, ...
What to do if you go lean with a blower?
If you go lean with a blower kiss the engine goodbye. You'll need to upgrade fuel system. At the min. you will need 1/2" pickup welded in your tank, and use 1/2" fuel lines.

with an 8-71 you better have LOW compression and very good bottom end parts. Roots blowers can't get away with the compression and boost that a centrifugal superchargers (pro charger, paxton, vortech), and turbos can.
Can centrifugal pumps heat up air?
Centrifugals you can get away with more becuase they're more efficient, don't heat up the air as much and the boost doesn't hit like a sledge hammer like it does with a roots. Probably in the 8.5-9 range. And an intercooler to this and you can go even higher.

What happens if a leaf blower head is cracked?
The cylinder head of your leaf blower engine is where all the compression is produced, and if the cylinder head is damaged or cracked, it can result in loss of compression. The only way to solve this is by replacing the cylinder head and installing a new cylinder head that fits the engine perfectly.
What does it mean when a leaf blower moves freely?
If it moves freely, then it is a sign that the sparkplug of your leaf blower is loose or the threading has worn out, causing loss of compression. In this case, you will have to replace the threading and the sparkplug of your leaf blower.
