Lawn mower loud bang?

Ryan

I buy lawn mower on craigslist for 500 dollar, brand is weed eater, it has 3hp tecumseh engine, it make loud bang after 5 minute of use and i dont know why. it also shoot fire out muffler and then stop. any answer appreciate many time. gracias

Answer
You paid $500 dollars for a used lawn mower. you can buy a brand new one at sears for 300?
Your probably paid for a $500 pos that was broken in the first place. Yet at this point you became a sucker, not only did you buy as is, You can't get your money back the Guy you bought it from, he just has to say it ran fine when he sold it to you.

Lesson here do your home work first, check prices at stores for the same brand before purchase
You could have got the same lawn mower brand new for less? Why would you buy a product that you have no history of? Now your out 500 plus cost for repairs or outright replacement.


Hope that helps

lawn mower help?

okiemom09

I have a craftsman riding mower. I was mowing and it started smoking. It is fine unless the blade is on. I think it is the belt. I looked on top of the deck and the belt looks like it has come loose. How do I fix it thanks

Answer
If it's Craftsman, that Sears brand. You can contact them or contact a local mower repair shop. They should have more info on releasing the tension on the belt and maybe replacing it. I found a lawn mower question site as well:

Replaced lawn mower transmission pulley?

TonsofFun

I replaced the pulley on the transmission of my lawn mower to make it go faster since it was just kinda sitting around not doing anything anymore. It goes way faster then it did before, but it will only go fast for maybe 5 minutes or so, then when i try to go fast again it doesn't go nearly as fast. If i wait a long time like over night, then take it out the next day, it works just as good as before....i dont know why this is. any help is appreciated.

Answer
This makes no sense. Only if the engine is overheating it MIGHT be the cause of reduced performance.

I know that all lawn mower engines have a speed governor. You demand power and the throttle opens wide. As the engine RPM's come up, the governor closes the throttle down a little to reduce its power. If the engine should be forced to run overspeed the governor will close the throttle down till the engine comes under control.

I used to have a mini-bike when I was a kid. I hated that governor, so I bypassed it. I disconnected the linkage between it and the carburetor. I then hooked my throttle cable directly to the carburetor and had FULL control over its power. Not satisfied with its power and speed my best friend and I built a supercharger for it. AND IT WORKED. We swore it had more power and speed but it may just have been the psychosomatic affect of BELIEVING it was working better JUST because we did something to it.

The power the engine is capable of generating versus the work you are asking it to do will have an effect on overall performance. If you over-stress the engine you will likely burn it out. Changing the gear ratios is a good way of trial and error testing to find what works best. But there's a limit to how fast it can go.

Be creative; try building an electric bike or go-cart. Electric motors can spin MUCH faster than gasoline engines. The only disadvantage is milage, you won't go as far. I toyed around with the idea when I was a kid but back then I didn't have my engineering degree and solving that problem was beyond me. If ever any of my girls give me a grandson maybe I'll build him one. But that's years away.

G-day.
