The machine is a Craftsman lawnmower with a Briggs and Stratton 190cc 675 series engine. This [url=http://www.hammerwall.com/Manuals/Craftsman/Description/917.376536/Craftsman%2022%20Inch%20Multi-Cut%20Self%20Propelled%20Rotary%20Lawn%20Mower%20Manual/L1001124/]manual[/url] matches my paper copy. I received the mower as a freebie recently and knew the previous owner had work done on it and was having problems. When I was trying it out, the engine would run poorly and then stop. I removed the air filter and could see the choke and see the mechanism that controls it. As the mower was running, the mechanism would move towards the green arrows, closing the choke. I would push back against the mechanism, forcing the choke to open up some, and the engine would come to life. [url=https://i.imgur.com/jX5ROsS.gif][/url] How should I go about fixing this properly? I only know of the two springs that I can see (I can see the one pulling on the choke mechanism running vertically in the image, and another to the right in the image, running horizontal, with unknown function). Neither spring seems deformed but they could easily be an incorrect spring.

Hello, I have soundproof 5kva generator which is using KM186f model diesel engine. Its 10hp Yanmar clone engine. It is quite hot in Myanmar with about 36C in day time during summer. I would like to install oil cooler in the engine. Has anyone done or any suggestions? After running about 1 hour, engine is hot and can't even touch it. I think it is normal for single cylinder diesel engines.
