Experienced gardeners share their insights in answering this question :
I think that noise is because your blades are loose. They should be tightened right away because they could come off when you are using it with the possibility of injury to somebody. I have serviced some mowers with that problem. They make more noise when starting because they are turning slow and moving around more than when turning at high speed. Best regards and good luck.
How to Identify and Fix Common Gardening Problems ?

Take a look at the blade under the mower deck. Sometimes the knocking sound you hear could be the result of a loose, bent or wobbling blade. If you`ve recently removed or replaced the blade and it suddenly started knocking, this is quite possibly the cause of your issue.
This can happen if you overtighten the bolt holding the blade in place, like I explained before – a damaged bolt won`t be able to keep your blade in position for very long. If this is the case, buying a new bolt should fix the problem.
The clicking noise comes from a part called the starter solenoid. The solenoid connects the battery to the starter motor when the solenoid is energized. The key switch and the safety switches in the starter circuit combine to energize the solenoid. If the solenoid is clicking, the circuit that triggers it is working.
A loud clunking noise when the starter is engaged in a car could be a sign of a bad starter motor or a damaged flywheel. Most likely the starter is loose on the mount due to loose or missing bolts.
A good rule of thumb for the average homeowner is to replace your mower blades annually. You may also think about replacing them if they become damaged. Dig up that product manual if you want a more clear-cut answer. Always make sure to take protective measures whenever sharpening your mower blades at home.
An unbalanced blade spinning that fast will cause a significant amount of vibration, which will put stress on yout blade shaft, spindle, and even the engine. So if you want to get the most life out of your mower… keep the blades balanced!
Signs of a Bad Starter Solenoid
It usually means there`s a faulty connection in the solenoid. Another common symptom is a single clicking noise when you turn the key.
If you have an anvil handy, you can put the non-bend end under the anvil and then use your channel locks to slowly and gently bend the blade back, so it becomes straight again.

I have a Poulan push mower that after mowing in a ditch started making a loud noise and running rough. It almost sounded as if metal was hitting metal. The mower was vibrating more than normal. I checked under the mower and nothing is hitting. After a few times of stopping the mower engine because it sound as if it is going to die down the mower will not start now. The shaft does not appear bent and the blade appears ok. The mower has oil, a good spark plug and a clean air filter. It was running fine until that moment. I did not see anything that I hit but it is possible I hit something in the ditch like a pine cone or branch. What could the problem be and how would I go about fixing it?
If you are sure the oil level is correct then it sounds like it’s about to die, unfortunately. A pine cone shouldn’t cause any damage, but a large branch may do so. Was it smoking before you shut it down? The vibration could be caused from a bent blade. It could also be caused from a part breaking in the motor. I wish I could have given you better news!
Lawn mower will start and run for 5 seconds and shut down
Will it stay running with your choke on? if so then clean your carb. if not then look for a blockage from tank to carb. ie fuel shut off, deteriorated fuel line. plugged filter etc
I have trouble starting a toro walk behind mower
All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!
I have had a poulan pro 550 series push mower for almost 1 year at the end of the season last year the mower would start briefly and then stop. i have cleaned out the air filter and that did not help.the mower started, i made one revolution around the yard 3/4th of the way the mower quit. I then primed the mower it started then quit and now it will not start at all. Does anyone have any suggestions of what to do. Thanks
There is a little spring that works the carburetor arm. If that popped off then the mower will not run.
It won’t stay running. have cleaned the gas tank and it just had a tune up. runs fine then gets rough and quits. If I push the bulb it smooths out and runs fine for a couple of minutes and then begins hesitating again. Now today it ran for about 15 min. and now it won’t start. It wants to. runs for a couple of seconds 5-10 and then quits.
Remove the float bowl and empty the contents out clean and replace
<!– from fixya rte –>Rj19lm plug gap for a 195cc 4cyl lawnboy – Lawn-Boy lawnboy" Mower Blade 21"
As a starting point in my shop i always use 0.30 in. For all my mowers
Self propelled mower will start but want stay running long? it runs about 3 or 4 min. then stop and when i restart it, it will start back up.
The fuel bowl has a float and needle, if the float isn’t floating to open the needle for gas to flow into the carb, it will cut off. A kit can be purchased for about $5 or take yours out and soak and clean then replace. Usually when these go bad its best to replace them.
I need to get the blade of the lawn mower sharpened.Any tips on how to disconnect the blade fropm the lawn mower?
There is a jig that you can buy that makes this job SO much eaiser. It is a universal jig that clamps onto the deck and keeps the blade from spinning so you can use a ratchet to remove the nut holding the blade on. One name brand is called a “Blade Hog”. You should be able to find one of these at one of the bog box hardware stores.
Hope this helps,
