Toro Power Clear 418 snowblower wont start after sitting through summer

Check the fuel line to the tank, and see if another one is inside, maybe it fell off, or it's filter is clogged.

I have a toro super cycler gts 5 model 20475 6.0 engine i put new gas in it a new spark plug but if i loosen the gas bowl no gas come out and it wont start what could be wrong

Ensure fresh gas is in tank. Follow gas line from tank to carb. Have locking pliers ready to pinch off gas line or close gas line valve. Remove gas line from carb. observe gas flow to carb. Remove carb bowl from bottom of carb. Attach gas line to carb. Does gas flow to carb. Observe float, float down gas flows, float up no gas flow. If float is bad replace float assembly or carb. Remove float mounting pin and needle metering valve. Use a bread wrapper pealed back an inch so thin wire can clean out port of meter needle. Use wire to clean out center port. Observe bowl screw look for hole thru screw, clean out with wire if preset. Re-assemble carb. Clean replace air filter. Fill oil. 30w. Prime motor, pull rope 10 times to start. No start, replace carb.

Ryobi 410 mini tiller w/Walbro WT149A primer bulb won't prime. New bulb, new fuel lines, hooked up right, carb cleaned. Been sitting for several years.Runs when fuel is pumped into the fuel inlet.

hello sir, my machine will only start when pumping primmer bulb or squirting fluid in the carburetor than stops. the fuel line has broken off, in most small carburetors this is a ongoing problem.old fuel will crystallize when left in tank for a long time.plugging up ports, fuel lines, small screen in carburetor.fuel lines will dissolve clogging carb.this is why it will run when the choke is on creating a vacuum to where there is fuel forced in the carb to rum,also the gas will evaporate leaving the oil behind clogging up carb.the thing to do is remove carb. and clean out,replacing gaskets or fuel line if necessary.use carb cleaner to clean out carb.make sure to make note where fuel line go.the fuel filter broke off of fuel line letting debris get in carb plugging it up.the muffler is known to clog up a lot on these machines where they want run. the compression should be 60 to 120 lbs any thing below 60 is junk. when adjusting the carb screws turn in all the way than turnout 1 1/4 turns turn in slow until machine runs also you need to check for spark by removing plug and grounding against engine to check spark, ok.a new spark plug would be a good ideal too , if you are going to make these repairs use new fuel line and filter,hope this helps,any comments welcome,thank you, !!

I have a craftsman DLS 3500 and my son put 2 part mixed gasoline in it and now it will not start. What should I do?

disconnect the fuel line at the carb and let it drain into something, then remove the screw(bolt) in the center of the fuel bowl and let the gas drain out...once it all removed, put the screw back in and hook the line back up..then remove the spark plug and use carb cleaner or something similar to clean the plug ...before you stick the plug back in after you have clean it, turn the engine over a few times to expel the gas oil mixture....refill the tank and try and start as normal...its probably going to some for a little while till all the oil is burned off

good luck

JD LA140 quit running all of a sudden. It was directly after I added older gas to it as the tank was almost empty. It won't even almost crank as if it isn't getting fire. However, the plugs are firing...

First thing. Dump the fuel! Pull the fuel line ahead of the fuel filter and drain it all off! Old fuel is sometimes accompanied by a lot of water. Especially if stored without proper container closure.

Next, drain the carb bowl. The carb bowl should have either a drain screw in it or the bottom of the bowl has a hex head fitting to allow the entire bowl to be removed. Take off the bowl and get rid all the fuel inside it. Look for water droplets that sit under the fuel on the the metal surface after the fuel has been poured off. If you have the bottom hex fitting type carb look at the barrel of this fitting. That is where you main jet is! You can use a fine piece of metal wire strand and clean out this jet. The holes are generally on the side *(if the jet has a bottom adjustment screw built in than it also has a hole in the center. Run the piece of wire through where you see dark spots and see if they clear out. Look through the jet and see if your handywork is allowing light through. *(yes? than you found a blocked jet and just cleaned it!

Now, put the bowl back on. reconnect the fuel line and put some fresh fuel in it. You might want to recharge the starter battery since you have probably cranked the battery down from all of this.

You can check for spark by getting another spark plug and using it as a tester. Leave the engine plug in place and just lay the tip of the plug on something meta/grounded and see if there is spark while cranking.
If you find spark this rules out a bad ignition system. Put the spark plug boot back on the plug on the motor and start it up!

If you can take off the air filter and look into the carb you might want to try putting a little bit of clean gas right into the carb opening. This will help prime the motor and perhaps get it running enough to eject the remaining water inside the intricate spaces in the carb.

Be careful and good luck.

2003 honda crf230f will not worked fine last fall.i put a new spark plug in it,cleaned the carburater,cleaned the air filter & changed the seems to have good spark but just keeps cranking...

IF you have a battery get a new one ; put in new gas ; super; dsid you ajest any screws on carb. You tight need to run a prime tank right to your carb to prime it; and then hook your tank backup new gas lines to your carb. Now break out with the WD40 to spray all switches for rust.
