Troy-Bilt

It takes a few pulls to start. After it starts, it must stay on full choke to run. It then surges the whole time, and dies after a minute or so. It has fresh gas and I have changed the air cleaner.
Experienced gardeners share their insights in answering this question :
Clogged fuel inlet line or fuel filter. It’s not getting enough fuel to run

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 :

If your lawnmower`s engine is surging it could be a problem with the carburetor. The carburetor mixes air and fuel to the perfect ratio for combustion. There are passages and nozzles (called jets) that route the fuel through the carburetor. The jets meter the precise amount of fuel that is needed for combustion.
One of the most common problems, especially because rototillers often sit unused for months, is stale fuel or a clogged carburetor. If you know you have fresh fuel, you can check for carburetor blockage by spraying a small amount of carb cleaner into the intake and attempting to start the engine.
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the engine for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
When soil is dry and compacted, tiller tines basically bounce off it without digging into it or turning it. Combat compaction by watering the area thoroughly one or two days before you till. Also, raise the tines to their highest setting so they till just the top 1 or 2 inches of soil.
Adjusting Tailgate and Skids

In order to adjust the depth of tilled ground you need to locate the skids on the side of the tiller and remove the bolts from both sides. This allows you to move the skid up and down to the desired depth. The lower the bolt hole on the skids the deeper the tiller will go.

Tiller: Why won`t my tillers wheels or tines turn? A broken drive belt, bad transmission or problem with the clutch cable can prevent a tiller`s wheels and tines from turning. Check the drive belt and replace it if it`s worn or broken.
There are a large number of reasons why your car might stall while driving. It could be a dead alternator, a bad coolant sensor or lack of fuel, just to name a few. Is your car stalling while accelerating? If so, then it could be a major vacuum leak, clogged fuel filter or a bad fuel pump.
For a tiller with a bladed wheel, push the tiller forward while it`s in the ground. This will rotate the blades and till the soil. For a tiller without the wheel, twist the tiller as you pull it straight out of the ground.
The Model number is eleven characters long and is printed on the left side of the Product Identification Label. Characters can include numbers, letters or hyphens.
It can be caused by various factors, fuel injection problems, bad spark plugs, a malfunctioning air sensor, might be a dirty air filter, and troubles with the engine control. Other issues of the fuel ignition system can also trigger surging when stopped.
There are several reasons that surging occurs. A restriction to flow or fouling in the air/gas system is one possible factor. This could be caused by a dirty charge air cooler, or dirt or contamination on a nozzle ring, for example.
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.
A wide variety of issues can prompt an engine surge. The problem may involve an annoying change (up/down) of engine speed while cruising at a steady pace, a low drop (or even cut-out) at idle or when approaching a stop, a wild high engine speed of several thousand rpm followed by a drop to near zero, etc.
Lawn mower surging is a result of either bad gas or spark plug, dirty air filter, or clogged gas cap vent. A dirty carburetor jet and fuel filter might also be the reason. You can also consider a carburetor gasket leak, which can be fixed by an engine starter spray.
Alternatively you can till hard ground with a rotary tiller, which is especially useful for medium-large plots. Use a rotary tiller of suitable weight so that it is stable and the blades penetrate deep into the soil.
With a powerful machine such as a tiller, you can level a large area and break new ground that will be used in creating a good planting bed or vegetable garden.
How fast can I run the tiller? It depends on the conditions, but 2-3 mph is about the right speed. You may need to slow down if you start to notice material building in front of the machine.
Consider this: A typical 5-ft rotary tiller with four tines can be run by a 25-hp tractor and the same 5-ft rotary tiller with six tines would need a 31-hp tractor to operate the tiller at peak performance. A 40-hp requirement jumps to nearly 50 hp with six tines.
Rotary tillers break through a variety of soils to create a workable area for gardens and flowerbeds. After repeated use, the tines, or blades, dull and wear down. No matter what type or brand of tiller you own, these blades will need to be sharpened or replaced to keep your machine working properly.
Whereas, reverse rotation tillers are heavy-duty tillers perfect for large-scale jobs. They are more effective in preparing seedbeds for planting, burying large clods of dirt as you go so you don`t have to take multiple passes to get the desired results.
If the rotary tiller still doesn`t start:

Check that the fuel tank isn`t empty: if necessary, add fuel. The fuel must be fresh, of good quality and clean: make sure that no dirt, water or incompatible fuel (such as petrol-oil mixture, if the engine is a 4-stroke) gets into the tank.

With the idle mixture screw removed, the tapered portion is what adjusts the volume of fuel allowed into the engine. Turning this adjustment screw clockwise (in) reduces the amount of fuel. Turning the screw counter-clockwise (out), increases the amount of fuel delivered to the engine.
Turn the idle screw to adjust the idle—turn the screw to the left to increase the RPM or to the right to lower it. When you have adjusted the idle—aim for 650 RPM—reconnect the idle air adjustment valve`s electrical connection. Lower the hood and turn your car off.
Among the potential underlying causes are vacuum leaks, EGR system malfunctions, malfunctioning oxygen sensors, dirty fuel injectors, fuel pump malfunction, faulty spark plugs, a faulty mass airflow sensor, or a faulty throttle position sensor.

Engine runs fine on 2-cycle Mantis tiller, but tines won’t turn when they touch ground. They turn when I start engine and when I “walk” the machine around, but if I try to till, they stop turning and engine sounds muffled. Engine sounds full power beforehand.
ANSWER : Your problem is a common one on Mantis tillers. The engine sounds like it is not breathing properly. I have fixed dozens of these problems and it is almost always the spark arrestor clogged up. The spark arrestor is found inside a small housing on the muffler (easy to fix). There are 3 screws that need to be removed to get the muffler cover off, then you will see a small housing a little over an inch long with another 3 screws…remove them and you will see a small screen that is probably clogged. Clean it and the housing with a solvent (I usually use carb cleaner) then re-install the arrestor and reassemble the muffler cover. This will fix your problem about 80% of the time.

If that is not the problem you may need to fix the carburetor (take my advice and just buy a new one…not much more expensive than the repair kit and a lot simpler.

Engine surges after warm
ANSWER : If your engine has an adjustment screw on the bottom of the carb. try adjusting that at high idle first also if you have a low idle screw. If that don’t clear the surging than you might have to take the carb. off and clean it. If cleaning the carb. out dose not do it you may need to put a new carb. kit in. Any questions feel free to ask.
