Say 'manual' but gives parts schematic and no carburetor

Hi
Sounds like you 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:
Write down on a piece of paper and or take a picture of how the linkage attaches to your carburetor for later reference when you go to reinstall your carburetor.
Mark each piece with a awl, or some kind of sharp 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 a very small shot of 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/s condition...after a while they will degrade and need replacement.
Check/Clean/Replace your fuel filter if you have one.
When you remove your fuel lines from the carburetor be sure to make a drawing or take a picture of how the lines are connected to the carburetor.
Also a good time to take a picture for later reference for reassembly.
If the mower 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.
Once you have your carburetor cleaned/rebuilt that should solve your problem.

The fuel line on the 141 is very small and wasn't really meant to be replaced for some reason, as it is a pinch fit. Buy the smallest fuel line you can, usually 1/8th OD inch fuel line. Remove the air-filter and the carburetor. You will need to drill out the
current hole a little bit, so go slowly. As soon as the new fuel line will fit _tightly_ insert the line. You will have to remove the hand-bar and the
anti-vibration bolts to separate the motor mount portion from the gas tank which is part of the hand grip.

Apply some gasoline proof gasket sealant to the space between the gap, else you will have a gas leak from the tank sooner or later.

Reassemble the grip and motor sections back together and let the sealant dry for a day or so. Put the carb and air filter back on and attach the fuel line to the carb and the other end to the fuel filter in the gas tank.

So it runs out of fuel when you are driving it and it stalls or you can't get it to pump anything to allow the engine to start at all?

Details vary with brand and model, but in general the fuel line goes into the tank somewhere near the carburetor and connects to the fuel filter inside the tank. The other end connects to the carburetor inlet-- usually near the upper end of the carburetor. Lower down on the carburetor, there is another port that connects with fuel line to the primer inlet port. Another line goes from the primer outlet back into the tank. Usually, one just goes to a saw service shop and buys lengths of the proper size line. Much cheaper than buying as a service part from the manufacturer. Hope this helps!

this could be a number of problems,check the voltage with a volt meter,not a test light at the fuel pump connection. make sure you have 12V,if so unhook the fuel supply line,turn key to ON not START, and make sure the pump will continue to flow,( obviously cqatch the fuel with a pail,or put a hose on it to pump it into a pail,don't let it leak all over the place.)if the pump continues to flow with out shutting off,your pump,filter,and electrical for your pump is ok.it could be a restriction in the return line,or the regulator may not be functioning.un hook the return line as close to engine as possible,install hose on it and route to a pail to catch fuel,with supply line hooked back up,start van and see if it works,if it keepd shutting off,you've now eliminated return line problems.check the regulator.

Sounds like a fuel issue. Just enough gas getting there to start it, but not enough to keep it running. Start at thefuel line to the carburetor. Make sure fuel will come out at a sufficient stream. If it doesn't, work backwards towards the fuel tank, looking for clogged fuel lines and such. Clean whatever is suspect. If you get fuel all the way to the carburetor, you'll need to clean the carburetor. Careful disassembly is critical to getting it put back together correctly. Clean your parts with brake cleaner, not carburetor/choke cleaner, paying particular attention to orifices.

1. Disconnect the negative battery cable.
   
2. Disconnect fuel tank hose at the fuel pump, and plug the hose with a bolt or wooden dowel to keep any fuel from flowing out wires. Check the hose and if it is frayed or cracked, replace it with new fuel line hose.
   
3. Disconnect the outlet line to the carburetor. Use a wrench on the fuel pump fitting and another on the line nut.
   
4. Remove the two attaching bolts and remove the old fuel pump. Clean off any old gasket material from the mounting surface of the engine.
   

Installation:

1. Apply a coat of gasket sealer on both sides of the new gasket. Put the attaching bolts through the new pump and slip the gasket over the bolts.
   
2. Install the new pump on the engine. Make sure that the rocker arm in the pump is against the eccentric inside the engine, or that the push rod is correctly installed in both the engine and the fuel pump. If the push rod slides out, you can pack it with some heavy grease to hold it in place while you install the pump.
   
3. Attach the fuel outlet line that runs to the carburetor. If it's difficult to connect, remove the other end of the line from the carburetor. Connect the line to the fuel pump, and then reattach the other end to the carburetor. Use a wrench to hold the fuel pump fitting and tighten the line nut with another wrench.
   
4. Attach the fuel inlet hose from the gas tank, and the vapor return hose (if the vehicle is equipped with one). Tighten all clamps.
   
5. Reconnect the battery ground cable, start the vehicle and check for leaks.
   

Hope that works
