Greetings, My name isXXXXX and I am here to help the best I can. My goal is 100% satisfaction. Let's get started.
The primer will not prime because the passages in the carburetor are plugged up
You need to clean and overhauld the carburetor
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.
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
Yes you may ask follow-ups, even after you hit accept. I will be notified via email of your responses.
If you think of it, it must be logical. What does the primer to. It is a Pump that PUSHES gasoline through a hole in the carburetor to where it can be carried into the engine easily before it is running and drawing enough air for the venturi effect takes over so it can "draw fuel".
If the pipe is clogged, the pump tries to compress the fluid (gasoline) which can not happen.
My toilet can look shiny and clean enough to drink out of (If I were a Dog), but if it is clogged, it will not flush and may be it is time for roto rooter or a snake.
