SOURCE: 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

Sounds like you need to take the carb. apart and clean it. I like to use a Den Tek Brush, (used for cleaning teeth), to clean the small ports in carb. they work great for this job. Make sure to either clean or replace the small screen in thcarb. as well.

Hi bdtyler72...
Sounds like you still have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:
Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by 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.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of weedeaters.
When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.
Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.
Make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the trimmer is over a couple of years old, then I 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.
The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or 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.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly 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 lightly seat them first and then turn them back out to their original position before you started.
Note:
The little spring inside of the carburetor goes under the float arm.
That is where your fuel inlet needle/float valve is located...on the arm at the end.
Normally there is a small indetion in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.
The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.
Once you have your carburetor properly cleaned and rebuilt that should solve your starting problem.

SOURCE: 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, !!

New primer bulb but engine won't prime


remove and clean the carby. clean out the main jet. ensure that there is nothing stopping the primer circuit from working. There are two valves under the primer bulb and a spring. when you push in the bulb fuel is squirted into the manifold When you take your finger off the bulb the spring pushes it out and new fuel is drawn past a valve to fill under the bulb. Pushing in again closes that valve and opens a second valve which allows the fuel into the manifold again

WE have rebuilt the carb and the tiller still runs for a few minutes then runs out of gas. We have put a new bulb primer, and we have new gas lines.


You definitely did good buy cleaning the carburetor and replacing the primer bulb. It is always a good idea to do that every 2 or 3 years.

But it sounds like it is probably a bad Ignition Module. Once the coil gets hot, it will stop working. You said it will run for a few minutes. How many minutes does it run before dieing?

I have model 3775R 2-cycle gas trimmer that has been working great for the past 8-10 years. After completing all required maintentance prior to this years cutting seasonit started fine twice already this...


check your fuel filterin tank and see if dirty, also you may have to clean the carb, normally the primer bulb pulls gas through the carb and back to tank, so if it stays down(primer) something possibly dirt is holding it down or try loosening gas cap and see if it pops back up and works right, if so your vent in gas cap is not working, if thats not it time for a carb clean/rebuild, Hope I helped You

I have a Husqvarna 455 about 2 years old. At about 1 year point it would no longer start using the primer pump button on the side when cold. If I take off the air cleaner and give it a a shot of gas down...


Your seeing the problem. Air in the fuel lines usually caused by a cracked fuel line or a pin hole in the primer bulb. Until you can stop the air bubbles by either replacing the actual primer bulb or fuel lines your always going to have the hard to start problem. This can also cause the engine to run lean at high RPM settings and eventually burn a hole in the piston. You should repair the fuel problem ASAP. If you do not find any fuel line / primer bulb problems then it is time to start looking at the carb diaphram.

Will not start. Primer bulb does stays pushed in.


that happens frequently on older equipment ... the alcohol in modern gas can damage the fuel lines and primer bulbs if used in tools not designed for it .. even replacing the damaged parts doesnt help .. since the replacement parts are often made of the same stuff as the original .. you have to make sure the parts can handle alcohol ... i dont take anyones word for it .. i soak them for a few days .. if they swell up or turn white .. then those are not compatable .. if you cant find alcohol resistant parts then you can still get gas that doesnt have any if you ask around .. ... if your tool is a more recent vintage then it should already be compatable .. maybe you have a clogged passageway in the carb or the primer bulb my just be aged .. if you cant get the primer bulb to work then you can try spraying a little starting fluid on the air intake (air filter) .. that should get you started to see if anything else is wrong .. if the primer bulb is damaged then chances are the plastic fuel line is also .. primer bulbs and other parts are usually available from the manufacturer and from parts supply stores ..
