Engine problems may have their root in something very simple. If your machine has a shutoff valve, check that first to make sure it’s in the On position. Next, make sure the engine has fresh gas. If the gas is more than 30 days old, replace it with fresh, stabilized gas. Next, check the air filter to make sure it’s not clogged. If the tank has fresh gas and you’ve primed the carburetor and set the choke but it still won’t start, it’s time to remove the spark plug. If the spark plug is wet with gas, it proves the engine is getting fuel. Dry off the plug with compressed air and examine it for signs of carbon buildup or oil deposits. Check the gap to make sure it’s within specs. If you have any doubts about the plug’s condition, replace it—they’re cheap. If the plug is dry, it’s a sign of a fuel problem and most likely a messed-up carburetor. Shoot a substitute fuel (WD-40 or PB Blaster Lawn Mower Tune-Up) into the carburetor throat and then try starting the engine (Photo 1).

If it won’t start or fire with spray fuel, you probably have an ignition system problem, most likely a bad ignition coil. However, if it starts and dies, that proves the ignition is working and the problem is fuel starvation. Check the fuel filter first by disconnecting the fuel line from the filter to the carb. Gas should run out. If it doesn’t, replace the filter. If gas flows freely through the filter, then the problem is inside the carburetor. Testing an ignition coil is a bit trickier. To do it right, you need a small-engine spark tester. Holding the spark plug boot close to the engine to check for spark isn’t a reliable test because a bad coil can produce a spark in open air but fail when the cylinder is under compression. If you own several small engines, it may pay to buy a tester To learn how to use it, read How to Test an Ignition Coil. However, since the tester costs almost as much as a new coil, replacing the coil without testing may be the way to go. All Leaf blowers Ratings

Two-cycle leaf blower equipment needs maintenance, particularly with regard to dust which can block air flow and foul the equipment. If you follow the recommended maintenance schedule, you are less likely to encounter starting problems. However, if the engine does fail to start, you can follow some troubleshooting steps to fix it.

Check that there's fuel in the tank if the two-cycle leaf blower won't start. Fill it if there isn't any. Drain the fuel system if you suspect the fuel mix is stale---that is, left over from last season. Take a look at the ignition lead and make sure it's not detached from the spark plug. Re-attach it if necessary. Take a look at the spark plug itself. Pull the ignition lead wire off the spark plug. abu backpack nsnHold it by the spark plug cap holder when you pull it. kaboom backpack obamaDon't just pull on the wire. khamski 38 backpackUse a socket set to remove the spark plug and look for fouling, cracked porcelain or broken electrodes. ericsson a2 backpack

Replace the spark plug with a new one. Un-flood the engine if you suspect it's flooded. Let it drain on its own, or simply remove the spark plug and drain the engine by tilting it. Clean the air filter, exhaust port, muffler, spark arrestor and vacuum bag regularly on a two-cycle leaf blower. The fuel cap has a filter that also needs cleaning. When storing any two-cycle engine-driven equipment for longer than a month, drain all the fuel from the tank.backpack hvor mange liter Ryobi Tools: Ryobi Blower/Vacuum Operator's Manualnike embarca backpack cheap The inevitable wear and tear on a leaf blower can eventually cause problems; fortunately, many of them are simple to repair.
