I'm retired now but I wasn't allowed to suggest any other fix than a new carb for this failure. Some carbs had a throttle shaft kit available but not the throttle plate.

By now the screw is either in the muffler or imbedded in the head or top of the piston. It shouldn't really be a problem unless it's imbedded in the edge of the piston where it could groove the cylinder. If you have or can get a small inspection cam you could maybe see inside the spark plug hole...

Screws might have come loose and the throttle plate is wedged in the carb.

You may have already checked this but, does the fuel line run anywhere near a high heat source? If so, see if you can re-route it away from that heat. You could be getting vapor lock. Another thing that can help if it is vapor lock is trying some premium fuel. Premium typically doesn't vapor...

Yeah, depending on how you look at it. It really shouldn't have happened on a commercial grade engine. For a lot of professional lawn folks, 494 hours is only about half a cutting season. :(

Does anyone else have issues with this website being really slow? I used to try and help out when I could, but it's gotten so slow at times that I can't even try to post anything. Thanks.

The clip breaking off the pickup tube was a rare occurrence and almost unheard of. If you can get a new tube and install it carefully you shouldn't have any issues IMO.

Did you notice any oil in the hose?

And it probably won't matter at this point as it seems you are not getting any fuel to the carb but remember, you need power to the fuel solenoid with the key in both the run and start positions. On these older units, the run circuit went dead when you turned the key to the start position. So...

Yeah, and it's not doing the intake valve stems and guides any favors either.

Will the engine idle without any choke? The governor should have no effect on a CV15 at idle. Even at high idle the governor should only affect the engine speed not the run quality. If it is indeed running lean, it's either not enough fuel or too much air. You can get the manual here free...

What are the engine models?

I've not seen any issues myself. Do you know if the customer ever tries to clean the air filter with compressed air? Also, if you haven't already, you might check the breather hose for being loose or cracked.

Hopefully someone has a solution for this issue. I inherited a Honda self-propelled walk behind mower, model HRR216K10VKAA. serial MZCG-1342918. The self-propelled works fine. The issue is, in the grass, the drive wheels simply slide on the grass when you pull the mower backward. They won't roll...

Are they? One says Kawasaki genuine parts and the other just says genuine parts.

With the carbs being set so lean in the last 15 to 20 years, having to choke a warm engine was not necessarily the norm but it was certainly not unheard of. On engines that were affected by that scenario the issue was there from day one brand new. It wasn't typically something that developed...

I can't speak to the quality of your Made In China Amazon filter but I can say, I don't believe you can get a better filter for your Kawasaki engine than a genuine Kawasaki filter.

I can't speak for Rehlko as I have zero experience with what they have done with Kohler but, Koher always advocated, if room will allow it, use the longest Kohler oil filter possible and fill the crankcase to the full mark on the dipstick and know how to do it correctly. Depending on which...

Does it use any oil?

About the compression, you have to remember that engine has a compression release so you're never going to see 90 to 120 lbs of compression. If you did it would probably rip the starter rope out of your hand when you pulled it. Tecumseh always stated that an engine with a compression release...

If it is indeed a Courage, it's not a CV493 so you may want to get a Courage manual.

Exactly, yes. Changing the name of the parent company is one thing, but changing the well-known names of the entities under the new parent wouldn't make sense.

What do you mean when you say you checked the breather valve? What were you looking for? What did you find? I guess what I'm asking is, how do you know the breather valve is good? What if you leave the hose off when it blows off? Does oil still come out of the fuel pump with that hose off...

For what it's worth, these are the companies there were under the Kohler Power umbrella when Platinum Equity made the purchase from the Kohler family last year. As you can see, it included engines, both gasoline and diesel, and Power Systems which was Kohler's generator and controls division...

I agree. Run it. There really isn't that can fail that would stop oil from getting to that area. Like ILENGINE said, it lubes through vapor mist. And if it helps. #1 cylinder is the one closest to the flywheel.

I know I'm a little late to this party, but have you found a solution? If not, look on the side of the carb for a round cover with one or two small rubber lines going to it. That's the accelerator pump. When you find it, if it has two lines, find the line that has the hard bulge in it. Once you...

Check for battery voltage to the solenoid on the carb with the key turned to the on/run position. Not all of the Courage single cylinder engines had oil pressure switches so that could be why you're not finding one. It sounds to me like you might be getting voltage to the fuel solenoid with the...

What were your compression readings?

Glad it wasn't anything more serious. Thanks for sharing what you found.

I guess to clarify, when you are checking for voltage at the B+ wire, where are you grounding the black lead of your meter? If you’re trying to ground it using the metal case of the regulator, then yes, a bad regulator ground could cause you to see no voltage on that wire. I always try to use...

The suspected bad ground would be if the regulator/rectifier is grounded. That would have no effect on DC voltage on the B+ wire.

Until you get battery voltage to the regulator/rectifier ground makes no difference. Once you get battery voltage to the regulator/rectifier, take your voltmeter, ground the black lead and touch the red lead to the metal part of the case of the regulator/rectifier. If you read voltage through...

You need to figure out why the DC wire shows no voltage. It should always at least show battery voltage. Right now, you have no connection to the battery, and you can't charge a battery you're not connected to. The violet-colored wire runs from the B+ terminal of the regulator/rectifier...

You’re welcome. Glad it worked. Hopefully it lasts.

No sorry. I wasn't saying the lifter shouldn't bleed off. They will bleed especially like ILENGINE mentioned if that particular valve stops in the open position once the engine stops spinning and puts pressure on that lifter. As far as how to adjust the rocker arms, there is no adjustment. You...

Depending on the model #, the head will have to come off to remove the lifters. If it will start after letting it sit, the lifter is probably bleeding down. I'd check the oil pressure before I didn't anything else. Again, depending on the model #, Kohler had a rare issue of too much oil pressure...

Folks will argue that they do it all the time and never had one fail but what they don't realize is, while it may not immediately fail, they have almost certainly just shortened the life of that coil significantly. So now a coil that really should have lasted the life of the engine fails...

😆

If it were mine, I'd be comfortable with 32:1 but that's as thin as I would go personally. And you may never really know. It may not immediately fail but it could shorten its life.

I'm still curious as to how many hours were on the engine. I've seen homeowners who ran their equipment roughly an hour a week for 30 to 35 weeks a year. At 35 hours a year, times 23 years, that's only 805 hours. A well taken care of Kohler Command should run 3 to 4 times that many hours. Oil...

This doesn't really help your situation but just FYI, that engine was built on the 270th day of a year that ended in 6, 76,86,96,2006. Tecumseh lets you guess which decade. It would probably be a little unusual for a chipper/shredder, but this wouldn't happen to have electric start would it? If...

Not just Kohler uses welch plugs. And years don't really mean much. How many hours did the engine run?

Do you have the original regulator? If it's OEM Kohler there is a part number on it.

Yeah that's right. I forgot that the oil pump was driven by the balance shaft. For some reason I was thinking the pump was driven by the camshaft. Does anything else inside the engine look worn? A couple of other things come to mind as well. With the rod cap being soft aluminum, I would think...

I haven't been inside a CV single in a long time, so feel free to correct me if I'm wrong here, but wouldn't the relationship between the balance shaft gear and the crankshaft gear keep the balance shaft from being able to move enough to contact the rod cap even if the balance shaft bearing...

What is the spec number on this engine?

Sadly no. It would require a complete crankshaft. It might wear in and quiet down. Or it might cause some teeth to break.

There does appear to be wear on the crank gear and virtually none on the cam gear.

Do you think the camshaft was replaced? If the camshaft was replaced, and not the crankshaft, that can cause noise almost like a rod knock due to the unmatched wear on the cam and crank gears.
