Just one of those broken bolts would have been enough for me. Nice job Rusty on the entire set of broken bolts. Thanks for the video. Now I’m ready to tackle my project with broken bolts.
You are so right patience is key when dealing with those busted bolts I blew it on my snowblower. One of the bolts for the starter broke of and I went to drill it out and ( you guessed it ) snap oh no ! Now I just pull start it what a tool ! 🙃
I think I’ll adjust mine to 4 also acting similar to what you described. I use left handed drill bits on those broken bolts and if you drill at a slow enough speed they might pull them out before having to use an easy out😊
Great job on a good video of an abused engine. 20 years ago I had a 18hp Briggs that wouldn't turn over with the plugs in, it spun well plugs out, valves were set correctly and engine didn't have an ACR measured cam shaft and 1 lobe was 2 thousands out of spec low ordered new cam shaft difference between the 2 was 5 thousands. Installed new cam shaft and the engine started perfectly/ ran beautifully. That one was also everyone said ACR was bad also. Good luck on that engine.
It was about 6-7 years ago before I started doing my videos on Silverados lawn equipment and motorized bicycles I came across a used Cub Cadet riding mower. It was cheap enough started right up when I went to see it so I gave the guy the cash and took it home. It would run fine as long as ya didn't cut grass with it the damn thing would just shut off and I would have to let it cool some every time. I ended up replacing both the coils twice no good then the carb then the damn PTO and finally after I bought another machine which I just sold. Well I ripped that briggs twin down. I mean soon as I got the pan off and peered inside it there was the problem. There was a childs friggin rubber super ball inside that Briggs engine. By the tightness and condition of all the bolts and other hard ware the thing had never been apart. The machine in appearance was like new. I think the guy that sold had done what I did is stuck it away and bought another and it came the day he needed money and sold it. But I didn't forget the machine or stick it away I wanted to know what the hell was wrong with it. I took the super ball out of the engine still have the damn thing in a drawer of my tool box in a little plastic container. It is there to remind me not everything is what it appears to be. How that super ball got in there at the factory who knows. A friend of mine worked at a plant where they used to work on & repair diesel generators for our state DOT. He said a couple times when the plant shut down for holidays or maintenance issues the crews came back & found critters that lived in the plant did some really weird shit to the engines and also including their tool boxes too. So it may very well not have been a case of human hands at all that did the super ball caper to that engine. Most plants here in the Northeast have cats that eat the rodents so like in the case here at my shop while my 4 legged buddies do their part killing rodents around here they also caused some incidents over the years up and including jumping right on top of a customers finish coated hood I just painted.
I had the same bolts break when i did mine. I set them to 5, and it was a little better. The battery had to be fully charged though and there was no room for cranking for more then a few seconds. Im going to go to .004 and see if it helps. My battery is dead right now. I dont want to buy a new battery or starter and waste money, so hopefully its just this.
Rusty, get some left-handed drill bit, they are not a silver bullet but they really help especially why drilling with an impact driver. I have been pleasantly surprised more than not!
I just went through the same issue with mine. Engine wouldn't crank when one cylinder came up on compression. That cylinder has almost 20 psi higher compression then the other. I finally figured out my starter was getting weak (worn brushes and a bad bearing), and that one cylinder had enough resistance to stall the starter. I've ordered a new starter.
It's not that simple I wish it had been for me before I went thru 5 starters. One thing that works 4 certain if the engine is not rattling from the valves being too tight is for one to use a 5W30 oil not a straight 30 weight or even a 10W30 sort of helps out. The one thing ya wanna do on a cold start is to close the choke completely like your instincts tell ya to do but do not turn that key. Back the choke off some let the butterfly slightly open you will have to get a feel for it. It seems my engine really jerks and tightens up if I don't leave that choke slightly open. It may cause ya to use a shot of starting fluid. I do that anyway but leaving that choke slightly open has ended the herky jerky starting and the engine locking up from the compression. A few times she has actually farted or fired off that ya get a little gust exhaust up thru the carb. I plan on ripping her down this fall I bought another 2ond and similar tractor a fella ripped his deck adjustment cable off and didn't feel like paying me to repair the thing so after I decided to call him he told me to give him $200 for the tractor and we would be square. I ordered the deck cable and I will use that tractor till business slows down and then I will get myself some real answers when I rip that motor down I will find out what is causes all the grief. I also do not have a clue and neither did Kohler on the diff between the SV710 SV720 and you know the SV730 they go all the way up to SV780 model so even Kohler itself could not tell me the diff between those designations. Possibly it is just the year of MFG who knows even Kohler didn't know. They are the same spec numbers as far as the 4 engines I have here but only one of em my primary tractor has that starting issue the other 2 tractors are customers. I included the tractor I bought has the SV720 but it is the same spec number as the SV710 in my primary tractor so I am miffed there... THE CHANGE IN OIL WEIGHT REALLY HELPED A GREAT DEAL IN THE STARTING. LEAVING THE CHOKE SLIGHTLY OPEN SEEMS TO BE THE KEY TO A SMOOTHER START UP. SO FAR SO GOOD.
How's she goin'? Nice research to get the Kohler to spin up like it should!!! I have a Kohler and it hesitates when starting too, so maybe I should check the valves and set them on the tight side too. That's a good idea!!! Nice job getting those bolts out!!! Take care!!
On busted bolts when I can I just might weld a nut on the end of the broken bolt. Between the heat and the new found leverage it normally does the trick
Good video Mr. Rooster! You deserve that cold one! I've had a tiny bit of luck with left hand drill bits. Though I doubt that would have really helped here with those really seized bolts.
I did snap an EZ out off in my Courage head....what a pain. Finally installed a Heli Coil insert after hours of grinding the darn thing away.Next time I think I'll find a way to insert a stud instead of a cap screw....
I recently had the same problem. When I pulled the valve cover off I found something disturbing. The top rocker was sideways....off the valve. When I pulled the pushrod out I found it was bent into a bow. Just great :-(
Yeah, ol-buddy, it happens. Make checking the valve lash as part of your normal maintenance at least once a year. Might help catch it before it happens again.
@@TheRustyRooster Yes I normally do this but as I am getting older it becomes increasingly harder for me to get up and down these days with the spinal injuries I have. I can do it but it sure is getting tougher. Unfortunately my son lives too far to get help from him and I hate bothering people. Now days I can't afford a mechanic (never needed one when I was younger). Enjoy your videos they are quite helpful.
Ok I have the same engine hard to get past a certain point I first thought of a briggs stratton cam how they have that advance mechanism,, so I guess this motor has nothing like that? So anyway Im going to try what you have done here and see what I come up with..
Wish you luck make sure you have good ground and battery connections. The new replacement starters have 9 teeth that helped also No compression release in the twin cylinder courage engines.
If it were a Kohler with bad ACR, would tightening the exhaust valve clearance still help it spin over easier, and would it be at the expense of a little power?
The manufacturer who make Kohler Courage engine's should be put in prison for making pure JUNK !!! Thee worst engine on the market for lawn tractors and mowers. Pure Shit !
Man tanks for watching, sorry you went through all that. Sure hope you get it going. They changed those starters to a 9 tooth to help with the slow cranking. Setting those valves made a big difference also.
