Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
Greetings, My name isXXXXX and I am here to help the best I can. My goal is 100% satisfaction. Let's get started.
You are describing classic carburetor problems
ok. wats next
I expect you have either a fuel Quality or fuel delivery problem.
But first, we need to know it has spark.
After trying to start the unit one more time,
Take the spark plug out, reattach the plug to wire to it and ground it to a head bolt. (When you had it out, was it wet or dry)?
If it is dry, we are 99% sure we are on the right track, but we still need to know if you have spark.
Turn unit on and either pull rope or engage electric starter. Look for a bright blue spark and see if you hear it. If it has spark, put a teaspoon of gasoline in the plug hole and reinstall the spark plug.
If the unit tries to start, but only runs until the gas you put in is gone then we need to look at cleaning the carburetor (especially if the plug was dry when you took it out).
You may get lucky and it may start and run. If so, let it. It may "clear its throat" or you may get some work done right now.
Most likely you have a fuel delivery or fuel quality problem.
As engines sit or get older, fuel that is left in the carburetor can turn to gum and varnish and cause this and other problems.
Also, any gasoline that was left in a gas can for a period of more than 30 days must be discarded because it also has begun to turn to varnish.
Today's gasolines contain MTBE and alcohol. (Ethanol) They turn to "Junk and garbage" very quickly. Alcohol absorbs water. And they call it "Oxygenated fuels! It is the oxygen (and the water) that breaks down the organic compounds in the fuel and turns the gas to "Garbage" (Gum and varnish) The fuels we had just a few years ago had no alcohol in it and would store for longer periods of time before going stale.
Fuel stabilizers do almost nothing to prevent the fuel from going bad with the changes in today's fuels. The whole point of a fuel stabilizer is to form an oily film on the surface of stored gasoline whether in the tank or in a gas can. The idea was to keep oxygen away from the gasoline to prevent breakdown. Since the fuel is already oxygenated, the fuel stabilizer concept is null and void. These fuels start to degrade immediately upon the addition of the ethanol.
Do not buy gas from the "Discount" Stations. The discount stations get a reduced price on gas because they may be buying fuel that is nearly 30 days old already. You may be getting fuel that's nearly stale right from the pump when buying from a discount station. Purchase your fuel from the well-known stations such as Shell, BP, Sonoco, Phillips 66 etc.
More than 70% of all of our repairs in our small engine repair business are due to these same issues. You most likely have dirt, gum, varnish...etc in your carburetor plugging up the small passageways and jets in the carburetor.
The carburetor will need to be cleaned and overhauled as well as the rest of the fuel system.
In an Emergency such as a blizzard where you cannot get out to buy a carburetor kit until the plows come through, or during an emergency power outage and you need a generator running even if it runs poorly, you might try the following if your carburetor is the type that has a bowl. Sometimes this procedure works:
While the carburetor is still mounted to the engine:
You may be able to finish the job at hand then clean and overhaul the carburetor correctly when you have more time and a new carburetor overhaul kit.
If you don't feel comfortable with these kinds of repairs, or if the carburetor still doesn't work correctly after your attempt, I would suggest sending it to a profession repair shop with a reputation for having friendly, knowledgeable, experienced service technicians. It would be best to take it to someone who has an "Ultra-sonic" cleaning machine. This machine uses a very mild carburetor cleaner in concert with ultrasonic vibrations to get the very small passageways clean. This method is very effective even when traditional methods fail.
Please feel free to ask follow-up questions so that we can always arrive at the correct solution. We want you to be 100% satisfied.

There is a new product that MAY help called mechanic in a bottle
The mechanic in a bottle is NOT a conventional carburetor cleaner.
It actually breaks down the varnish into it molecular components and it completely dissolves. It DOE NOT clog up the jets as conventional carburetor cleaners do. Conventional carb cleaners just loosen the varnish and the varnish particles will go into the jets and filters and clog them up.... usually causing much more problems that was originally there. The conventional carb cleaners also will loosen the "GUMK" that has formed in the gas tanks and cause all of that gunk to go through the carburetor as well.
The Mechanic in a BOTTLE is a completely revolutionary product that will in many case alleviate the need to tear the carburetor down and rebuilt it..... unless there is mechanical wear and tear that would require that parts be replaced.
In addition, the special formula actually is designed to soften and restor the rubber parts in the carburetor such as the needle and seats and gaskets.
Mechanic in a bottle is NOT a cure-all but it can help customer get going in many cases without them having to tear the carburetor apart. If the customer is NOT mechanically inclined, it might save them a trip to the repair shop.
Yes I was very skeptical about this product when I first was introduced to it, but the Distributor demonstrated it and we have tried it on many occasions with terrific results.
it now will only run on 1/2 choke. When I turn it to run it cuts off.
I am sorry was multi tasking
an giving you time to read
I 100% expected that it would run only on 1/2 choke
it is not getting enough gas
where do I get the mechanic in a bottle at? I'm in North Carolina
check also to make sure the fuel filter in the tank is new and not clogged
it is so new, it may not be everywhere yet
mail order yes
also check to make sure primer bulb is not cracked
and fuel lines do not have tiny cracks or slits
i just changed the primer button with a new one. It was cracked.
better to clean arb and use carb kit, but if you can find it I would try it
if the primer bulb was cracked it was probably because of old gas and the carb is varnished up
I know you can get mechanic in a bottle from www.oldmowerparts.com
so I really need to clean the carb
you may have to email them firstname.lastname@example.org
I haven't done it before but I nwill try to take it apart
if you screw it up the carb can be repalced for about $50 or so
what brand is the leaf blower
and how old is it
also, please do not forget to hit ACCEPT before you leave or I do not get paid
its about i year old and says bweedeater b25cc gas no other name on it. I got it from lowesa or home depot
i will hit accept
I will still be available
for followups via email as well
how do I get back to you?
You need to decide if this is worth fixing for you
ok its just a year old
just come back to this same location
Mechanic in a bottle just signed nationwide contracts with Walmart and Home Depot.. You should be able to buy it there.
I am changing my answer to say..
Try this first, make sure to let it sit for at least 8 to 24 hours
Empty the tank 100% first
then put the whole tiny bottle in
then pretend to try to start it and run it for about 30 pulls on full choke
if it starts and runs (it should not) keep it running for 60 seconds
then turn it off and let it SOAK
then come back to it and put a cup of gas in the tank
This time start it and keep it running as long as you can
it will either start running smoother or not.
If after 2 minutes of keeping it running, if there is not improvement, stop it and let it sit for another 8 to 12 hours.. If there is improvement Keep it running and do work with it. It should get better.
If it did not improve after 2 mins, stop it and let it sit for 8 to 12 hours like I said above.
then try again
This time keep it running as long as you can..
Even using it to blow with..
Lastly, if this did not fix it, then fill the tank with gas, and try again.
See if you can gt it to run a full tank through..
If not, then you must clean the carb
