Pull your sparkplug out and make sure you are getting spark, if you are getting spark then proceed:
Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor or follow the instrucitons you get with the carburetor kit.
If the mower/weedeater is over a year old, then I also recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, you will first need to seat the jet screws.
But before you seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to seat them first and then turn them back out to their orginal position before you started.

I put a mixture of oil gas in my 621 R/621 toro snowblower?


Hi Jerome:
Shouldn't be too bad.
You could disconnect the fuel line at the carb and drain the tank.
Drain and flush the carb. Reconnect the fuel line and fill with fresh gas.
If it won't start, pull the spark plug and clean/dry it with a propane torch, or replace it.
Odds are it will be fine.
Cheers.

The motor won't start


Older Homelite's love fresh fuel. Mix up a fresh batch of gas with the recommended oil ratio. Dump out the old gas into an approved container. Remove the spark plug for inspection and make sure that you are getting a good spark. If you are getting a good spark replace the plug and pour some fresh gas mixture in to the tank and follow the manufacturer's starting instructions. Generally they have a primer bulb press that in 5-6 times until it gets firm. Engage the choke and pull on the rope until it attempts to start. Turn the choke off and it should start right up.
If you did not have a spark on inspection replace the plug and repeat the process.

Have to run engine with choke pulled out fully


The flow of gas is restricted. It might be debris, but it is likely to be gummy gas. Get a can of carb cleaner, empty the gas from your mower. Mix a small amount of 50/50 carb cleaner and fresh gas. Start it up. Once it starts, or if it fails to run on this mixture, once you have pulled it enough to get the mixture all of the way through the carb, shut it off and let it soak for an hour or so. Then run it again. If it seems to run better, just add more gas and you are in business. If not, try to run the rest of the mixture through before adding more gas. If this clears it up, the problem was gummy gas. Use fuel stabilizer in the future (like Sea Foam). If this doesn't fix it, you have debris in the carb and you will have to disassemble the float bowl and clean it manually. Good luck, Al K

Have two blowers.....both under two years old...both wont start...kept clean, use proper fuel mixture and all...what gives?


did you drain the fuel out before storing for the winter? this is most common mistake, therefore the fuel gels up in the carb and lines I would ,first does your primer bulb work does it fill with gas? If so pull the air snorkel off so you can get a squirt of carb cleaner in there to see if it will fire up and run, playing with the choke when it does start keeping it running to pull fresh gas into carb, also would'nt hurt to check your fuel filter in tank

After starting and operating the chainsaw for a short time, it dies and I can't get it started again. Suggestions?


Engines require 3 things. Spark, compression and fuel. And chainsaw need 2-cycle oil mixed with the gas.

Assuming you have the right oil-gas mixture and a fresh batch of gas, and you didn't leave old gas in the saw all summer long since last November.

-Take off the dirty air filter and see if saw starts without filter. Do not run without putting in new filter.
-Check exhaust port for mud dobber home or screen clogged with carbon and dirt
-See if saw fires up after squirting WD-40 directly into carburetor
-Check gas line >>> pull gas line loose and see if gas flows out of tank to carburetor
-Take out spark plug > put finger over spark hole and pull cord >> do you feel suction that says you got compression?
-Put spark wire back on spark plug >>> hold spark plug so threads touch bare metal part of spark plug hole >>> pull starter cord and see if spark shows between plug and saw >>> suggest you not hold metal part of spark plug while pulling cord [you'll understand why]
-If spark plug shows spark, then your saw has spark ... so put in new plug and start fresh.

If your saw has compression, spark, and fuel it should start unless carburetor is gummed up because gas was left in tank.
Here is the final trick. Start the saw while spraying WD-40 directly into carburetor and see if you can keep it going with the WD-40. This might take a helper. If this does not work, then carburetor is bad or gas line is clogged at carburetor. Time to take it to the shop.

Husqvarna 20" 359 wont start. Has spark. the gas and oil were mixed and left in a plastic vented can in the hot sun. came back a day later and half the mixture evaported. Could the gas have evaporated and...


You are correct. Too high a fuel to oil ratio will not asallow the engine to run. Try using a fresh mixture of the correct ratio. It may take a lot of pulls on the starter until the old fuel is purged from the carby.

Willnot start no matter what new plug fresh gas


90 %of the time its a fuel problem either it turns stail and clogs the carb or the wrong oil/gas mixture etc, try this first dump out your gas can and refill it with the proper mixture use PREMIUM GAS then fill tank remove air cleaner prime fuel line r&r spark plug with new one then shoot a little starting fluid as you start it if you can get it running alot of times you can blow out the gunk/gum causeing the problem? if this dosnt work i would probbably toss it for a new one ? the repair bill will cost more than a new one ? hope this helps

My Poulan 3500 chain saw will not start


My guess is that one of your fuel lines has a crack or small hole in it. Inspect these and replace if needed. let me know how it goes.

Chain saw starts with starting fluid only but will not run.


Hi lwhssh:
Suggest you drain the fresh gas/oil and add a fresh batch but first add a gas stabilizer to your batch of gas/oil in the storage container. You will probably still need to use starting fluid for a few times When 2 cycle engines sit for a long period of time, the gas/oil mixture undergoes a change and tends to leave a residue on the delicate parts of the carb. The gas stabilizer will help that.

I always do the following for 2 cycle engines when I put them up for the winter. Empty the gas container on the device and then start it to use up any gas left in the fuel lines and carb. this keeps any residue from forming.

Hope this helps Good luck Loringh PS please leave a rating if appropriate. Thanks

Staring difficulties


I don't mean to over simplify this, but are you using fresh gas? Gas string trimmers are extremely ticky when it comes to gas. They like it SUPER fresh. And while the gas and oil mixture should be right, it can be off a little bit and still run. Try draining all of the gas out, and then filling up with fresh mix. This is ALWAYS my first step with string trimmers, and it fixes the problem 75% of the time. Also make sure your spark plug is clean. If you are not sure, a new plug couldn't hurt.
Hope this helps!!
