Prime bulb for 10 pumps, still see air going back in the return line. Carb is not primed won’t start, put a little gas directly in carb, starts and runs but is smooth at 3/4 throttle dosent reach full rpms. Idle lasts about 30 seconds and then dies. Repleaced fuel lines, and fuel filter and primer bulb. Rebuilt carb, cleaned primer valve. at a loss as what is the problem
Experienced gardeners share their insights in answering this question :
Look inside the tank. Some units have a stone inside that blocks the fuel line when it is tipped a certain way. Might be what’s happening here.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Primer bulbs do not work well if there is lots of air and no fuel. I spent over one hour getting my new boat primed. You might try running the hose and bulb to a can of gas (lots of things can go bad with can of gas, be careful) and see if the motor will fill and firm up the bulb.
If your 2-stroke brushcutter fails to start, the simplest explanation is that there is not enough fuel: in this case you simply need to top it up. A 2-stroke brushcutter engine runs on fuel/oil mixture, which you can buy ready prepared, such as EFCO-Mix Alkilate alkylated mixture in a 5 L can.
The fuel filter might be clogged. A clogged fuel filter is most commonly caused by leaving old fuel in the hedge trimmer. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and prevent the engine from starting.
ANSWER: The primer bulb, which is located in the fuel line between the gas tank and the engine, is used to fill the carburetor with fuel when the engine is started cold.
A primer accidentally left open will cause the engine to run rough after starting.
If you`ve used the correct procedure to start your Stihl trimmer and it does not start, the problem is likely related to either the spark, the fuel or the air circulation in the combustion chamber. More often than not, it`s an easy fix, possibly involving replacement of a spark plug or air filter.
Since the primer bulb is now not pressurized, if you pumped it, you would be able to do that. It would get firm for a short period and then loose pressure and return to a vacuum state. This is perfectly normal. What is not normal is for the primer bulb to collapse either with the engine running, or not running.
Depending on how often the little machine starts and its age, the inside of the bulb will eventually get gooey, causing it to stick. If a brittle bulb cracks around the seal, air will leak out the side rather than force fuel from the tank into the bulb, also causing a collapse.
The air filter may be clogged or dirty. If the air filter is clogged, the engine will get too much fuel and not enough air. As a result, the engine may stall. If the air filter is clogged, replace it.

Turn on the ignition switch and pull the starting cord quickly. You should see a spark in the plug gap. Since the spark may be faint, it may help to do the test in a dark area. If there is no spark, check for a broken or shorted (bare) lead wire or bad switch.
If your trimmer engine idles, but stalls on throttle, check the following parts: the gasket, primer bulb, fuel filter, air filter, fuel vent, fuel line, and carburetor. The repair and symptom guide will help you better identify the part needed to be replaced and how.

It starts and runs for a bit but as soon as it hits thicker grass it dies
ANSWER : Joe Hi there. Sadly your trimmer will struggle on thick grass as it’s not made for it. You could try moving the trimmer like a scythe. This will aid it as your cutting bit by bit.

Mower won’t start
ANSWER : This may sound stupid but don’t mean it to…
Have you tried with the choke all the way open? Do you have an automatic cruise? Is the right (correct) pedal being pushed in? These will affect if it starts or not. Also if your drive belt or one of the other belts not being tight enough will affect if it starts or just turns over. Not too many things can stope it from starting with new/good battery AND if its getting gas. Try cleaning your gas line and obviously making sure there is no obstruction around or near your blade, if it does start with blade engaged that is :))
If it doesn’t start with blade engaged, well make sure it’s in neutral. Mine won’t start in reverse but will in forward or neutral.

My mower will start but won't stay running – Toro LX466 22HP Lawn Tractor 13RT61RH244
ANSWER : I am going to respond 2 times to this post. The first reply will be generic things to check.
First off check the oil level and make sure it is serviced to full.
If your having a lack of fuel (runing lean) you will need to check fuel flow at the carb fuel mainfold. It should fill a spray paint can lid in less than 10 seconds but teting flow rated of the main fuel line. If you have poor flow here… you need to check the fuel filter and the fuel tank outlet port for obstructions.

Good Fuel flow still shutting off…. remove the carb float bow and clean the debris from the bow’ and the treaded area where the fuel solenoid mounts Additionally you will have to again remove the main fuel line and spray carb cleaner in the float needle area to flush out any debris through the fuel hose connection.
For the second response I need to know which engine is installed on your mower by MODEL number if you can locate it. (there are 3 engines) At least try to find the engine model number. If you can not locate it Brand and HP of the engine (I assume 22 hp) Thanks for choosing FixYa,
