I managed to find a brand new short block for a 1983 Toro Blower Vac 62923. After putting it all together, I tried to start it, and although the recoil starter will start the engine, I had to pull the rope a couple of times to get it to retract, and when it was stuck with the rope not recoiling, it really let out a metal on metal howl. I watched a video on removing it and cleaning and lubricating the small clutch that is held on to the flywheel by 4 sheet metal screws. I did all the clean up of the parts and channels, but the video was not very clear on the lubrication of the rectangular part of the clutch that actually engages the plastic recoil wheel. I drowned it in WD40 and force fed some into the front of it where there is apparently a felt pad behind a small hole. It is working nice and quiet now, but I'm thinking that the factory put some other type of lubricant in there. It lasted for over 40 years so it must have been good stuff. Does anyone know what Briggs might have used in this application?

The machine is a Craftsman lawnmower with a Briggs and Stratton 190cc 675 series engine.

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.
