The gas is going into the the crankcase. When the piston goes down it opens the ports and allows the gas to go down untill it could fill the crankcase. Start by blowing compressed air into the spark plug hole and allowing the piston to go to it's lowest position. This will usually remove any liquid gas from the crankcase. Next get yourself a small spray bottle and fill it with the same gas mixture your trimmer uses. Now you can spray a small amount into the spark plug port, replace the spark plug, full choke and pull till it pops. set to half choke and pull. I have also sprayed into the carb but you must open the throttle to allow the gas to enter the combustion chamber. Spray,close throttle,pull choke and pull. You may need to do this a few times for it to start. After it starts let it run at half choke for awhile until it warms a bit then open choke and go to full throttle. If this dosen't work it's possible to have other problems.

Engine wont start

Here's a little trick that always works so long as your spark plug is in working condition. Remove the spark plug and pour a small amount of gas into the spark plug hole...I usually take the cap off of a tube of toothpaste and fill the cap with gas...it seems to be the right amount. After pouring it in, put the spark plug back in and start it up. If there is debris in the carburetor this will usually dislodge it through the vacuum of the running engine. Hope this helps : )

I have a 3105 Toro trimmer that won't start. Things I have tried is replacing the spark plug. Trying fresh new gas. I have checked for spark and seems that it shows spark . Can you help me?

If you can get it to fire by adding a small amount of the fuel/oil mix directly into the air intake, then you have a fuel system problem and either the carb or fuel line are at fault. Depending upon the amount of use the trimmer has had, it can also be an ehaust port constricted with carbon.

Bought this lawn mower.It was sitting for two years and now it won't start.

first things first:
1) make sure that the kill for the magneto/coil is breaking contact( it is on the side of the mower,follow the cable down from the red bar)
2) gas to carburetor
3) spark to plug/s
4) gas to cylinder/s

pull plug and try starting mower, observe spark plug for spark and fuel coming out of cylinder/s. if spark no gas, then check to see if it getting to the carburetor, if it is then it is the float and seat in the carburetor and will need to be cleaned/replaced/rebuilt. Or just simple pour gas into the carburetor and try starting if it starts then it is the fuel line, carburetor. Hope this helped Tim

25cc Craftsman line trimmer: - will not start. - no spark across the gap of the plug - plug shows no corrosion.

Hello there and thank you for choosing fixya
normally on these when you dont recieve a spark and you are 100% sure that the spark plug is good than the only thing left to check is the ignition coil
It is what the plug wire is connected to kind of a square or round part these are nortorious for going out in small engines this is a 35 dollar part ok?
thee if this does not do it check the on off switch for continuity
Then finaly Check the flywheel cover, the magneto gap and starter coil if there's still no spark.

I have a Husq. 326 L trimmer; my pull cord seems to tug and becomes almost unpullable and it wont start; I have a new spark plug-what could be causing this?

Pull your plug back out and see if your cylinder is full of fuel, if this is the case your needle/seat is leaking fuel into cylinder causing hydrolocking (gas won't compress) good luck

Stihl Gas hedge trimmer will not start after sitting idol for some time (4 months) with gas in ti.

Purchase a new spark plug. Pour all the fuel out of the tank and fill it with a fresh supply of fuel. Now, remove the spark plug and spray a small amount of carb cleaner in the combustion chamber. Quickly install the spark plug and fully close the choke, press the primer button 3 times and try to start it. You may have to do this several times until it starts and runs.

2 Cycle Gas Trimmer will not start

it is normal to see air bubbles in line when pumping the bulb. to make sure what the problem is, try starting several times, remove spark plug. if dry, yes no fuel, remove the carb. if wet, place plug on engine block and look for blue spark. no spark means you need new plug, plug cord or ignition module
