Troy-bilt Backfire now won't start. Thread starter Air87 Start date Jul 13, Air87 Forum Newbie. Joined Jul 13, Threads 2 Messages 7. I bought it used and had issues with it from the start.

I finally got it working yesterday but when I was finishing my side yard I was going up a hill. It got stuck in a hole so I went to shutoff the engine so I can push it out. When I did it backfired and then the engine cut off. Now I can't turn it on at all. It doesn't even turn over.

I turn the key and nothing. No sound from the engine, no moving, nothing at all. What may be the problem and will I be able to fix it? Any help will be greatly appreciated. Here is some additional information about the engine. Model: Type: E1 Code: ZE not sure about the last two digits they were hard to read. Boobala Lawn Pro.

Troy-Bilt Blade Removal Tool.A mower th at backfires is irritating, but thankfully backfiring is not a danger to your engine and lawn mower. So what is a backfire, what causes it, and how can you stop your lawn mower engine from backfiring?

A backfire is a popping noise caused by gasoline igniting outside of the combustion chamber of the engine. A backfire is often caused during rapid deceleration, as the engine tries to bring its timing in line with the lowered throttle. This can often lead to an excess of air in the mix, creating a lean blend. The lean blend is then forced into the exhaust system due to incomplete combustion because of the mistiming, where it spontaneously combusts with the popping sound that is heard.

This sounds like a lengthy process, but in fact occurs in a split second due to the precision timing of the engine. There are a number of things you may do while operating your mower that can cause a backfire, and there are way to avoid them. The primary cause of a backfire is decelerating too quickly. The simple fix for this is just to lower the engine speed a bit more gradually. If you have a throttle that you use to reduce speed, gradually let it up instead of letting it rebound quickly.

The second most likely cause is a carburetor that is not adjusted correctly. The carburetor itself could be producing a lean mix, causing backfire during normal operation as well as during deceleration. Sometimes the gasoline itself is the problem.

Mowers are engineered to handle certain blends of gasoline, using the wrong blend can unbalance the system. To fix his, simply change your blend — try to find a no-alcohol blend, or at least a lower alcohol blend if a no-alcohol blend is not available. Another cause of backfires can be the engine running at a hotter temperature than usual, which is simple to fix by increasing airflow over the engine to cool it down, or stopping the engine and let it rest.

For a long-term fix, consider modification of the engine housing for less air restriction across the engine. Finally, sometimes backfires simply happen due to the construction of the muffler, and the sensitivity of internal passages. In these cases, short of replacing the muffler, there is no fix.

Explore the Lineup Get Closer.A lawnmower backfire makes a surprisingly loud noise, catching you off guard when you're wrapping up your yard work and shutting off the lawnmower.

Troy-bilt Backfire now won't start

This backfire occurs when fuel ignites outside the engine, usually in the muffler. The backfire won't hurt your engine, but it's often a symptom of a mechanical problem. Backfiring might occur right after your lawnmower engine shuts down. Several reasons exist, including incorrect carburetor settings and problems with your muffler's construction.

Getting the carburetor and muffler checked allows you to make adjustments as necessary. The problem also could be the type of gasoline you're using. Gas containing alcohol ignites differently than non-alcohol gas, which means it could ignite in the muffler instead of the engine.

Changing to a low- or non-alcohol gas might solve your problem. When backfires occur as your lawnmower idles or as you're turning off the engine, the most likely problem is that you're slowing your engine speed too fast. Moving quickly across your yard builds up the engine speed, and if you shut it off suddenly, the engine could pump gas into your muffler where the gas could ignite.

Slowing the speed gradually and allowing the motor to idle for 15 seconds before you turn off the mower can help reduce these backfires. The problem also could be that your mower is overheating; if you suspect this, contact the manufacturer about ways to increase air flow to the engine.

Lawnmowers shouldn't backfire when you're trying to start them. This often is a sign that the mower is damaged in some way; for example, you might have run over a large rock or other obstruction.

Many mowers have safeguards in place to allow inexpensive items, such as flywheels, to break when the blade hits a large obstruction; these parts basically sacrifice themselves to save more expensive ones, such as the crankshaft. When a flywheel is broken, your mower might stutter or backfire when you try to start it, but it won't completely engage.

It's unusable until the flywheel is repaired. When you notice backfiring occurring as you try to start the mower, take it in for professional repair before trying to start it again. Some mowers include special parts to help prevent backfires that occur after you've turned off the engine, called anti-afterfire solenoids.

These allow you to turn the engine off at any speed without excess fuel shooting into the muffler. Troubleshooting and replacing anti-afterfire solenoids needs a professional's touch, so contact a licensed repair facility if you think a non-working solenoid might be the issue.
