Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
I have already did everything you suggested
Thanks for trying to help anyway.
The most likely cause of your problem is that when you cleaned the carburetor, you did not use a complete carburetor repair kit. It is most likely flooding the engine from fuel that is leaking past the float needle. Replace the needle and seat (It is in the carb kit) and make sure that the float is set correctly. It should be mostly level with the carburetor body.
If there are adjustments on your carburetor, The one on the bottom of the bowl is the high speed jet and should be adjusted at 1 1/2 turns out to start. then adjust till it runs correctly.
The idle adjustment screw is on the side of the carburetor...just above the bowl. It should be adjusted between 3/4 to 1 turn out to start. Then adjusted from there.
I am sending you my standard carburetor answer and also a copy of the Tecumseh service manual for you to look at.
Tecumseh l-head service manual.
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 gasoline's contain MTBE and alcohol. (Ethanol) They turn to "Junk and garbage" very quickly. Alcohol is partially water (H2O). And they call it "Oxygenated fuels! It is the oxygen 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... and fuel stabilizers do almost nothing to prevent the fuel from going bad with the changes in today's fuels.
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 lawn mower business are due to this same issue. You most likely have dirt, gum, varnish...etc in your carburetor plugging up the small passageways and jets in the carburetor.
The carburetor must be removed from the engine. Clean all parts with carburetor cleaner and blow out all the small holes and passageways with compressed air. Remove all of the non-metallic parts since the carburetor cleaner will cause them to be disfigured decompose and plug the carburetor as time goes on.
Wash the carburetor cleaner off of the metal parts by washing them in warm, soapy water then rinsing with clean water. Dry them by blowing it off with compressed air. Make sure that all the passageways are blown dry before reassembling.
Reassemble using a NEW carburetor rebuild kit.
DO NOT TRY TO REASSEMBLE WITHOUT USING A COMPLTE CARBURETOR KIT! You will just end up having to do the job again.
ALWAYS clean the fuel tank and replace the fuel line when doing this repair or you may have to do it all over again. The inside of the fuel line disintegrates over time and these small pieces of rubber will plug up the carburetor too. Dirt and water from a dirty fuel tank will also plug up the carburetor. Find the Model, type and serial or code numbers off of the engine and take them to your local dealer to get the carburetor repair kit.
If you do the work yourself, take pictures or at least make a drawing of where all the linkages, gaskets, and component parts go. Correct reassembly is critical.
If the carburetor still doesn't work correctly, you may have to take it to someone who has an "Ultra-sonic" cleaning machine. This machine uses carb cleaner and ultrasonic vibrations to get the very small passageways clean when traditional methods fail.
If you don't feel comfortable with this kind of repair I would suggest sending it to a reputable shop.

Thanks, XXXXX XXXXX have already did all of that
I have already asked for a refund thanks again for your time.
I wish you luck,
At least th repair manual should give you some ideas. There is obviously something wrong with the carburetor or maybe even the valves. This manual should help.
Just a note to you so you will know in the future.
We as experts are here to provide information that is supposed to give you some ideas on what you may be able to do to find out what you might do to correct a problem. It is actually our time that you should be paying for. We are NOT here to completely solve your problem for you. That is ultimately up to you. Just because you did not solve the problem from our answer, does not mean that we did not do our job. Remember, we are not looking at your piece of equipment and can only give suggestions based on the information given to us by the customer. There are many different variables that can enter into what may actually be wrong with the machine. It is not the same as taking a machine to a repair shop and expecting the repairman to completely repair the unit. Again, we are just trying to give a customer IDEAS of what MIGHT be tried.
And if I can be of any more help in the future, pleas contact me again.
Thanks, XXXXX XXXXX but with both experts I was told the same things I had already tried. That is the reason I put in for a refund.
Thanks again for your reply
I also realize what you said, but it is most likely that both experts were correct. It is very possible that if you were to actually rebuild the carburetor again, you would find the answer this time. Just trying to help.
