16 horse won't start again

[The Tuul Crib 7,332]

 So I've got this 16 horse setting on lRV

And Saturday finally got everything hooked up with some gas in it and it started right up after a few cranks  of course.  The motor sounded good at first but I did detect a little tappet noise and didn't give it much thought. So went ahead and adjusted the governor and hooked up the linkage get it already to go and Sunday morning went to crank it and it turned over and shot gas out 

the carb .  Now it acts like there is too much compression with the plug in it And can't get it to crank over. So I went back and checked the valve adjustments and reset them correctly  with only the same thing . Any ldeas?

Haven't got it hydro- locked have you? Take the plug out and crank it over for a few seconds. If it's locked up , most the time it's too much fuel in the cylinder .

No hydro on this one.  There has been some battery discussion amongst some others I have talked to and I may not have paid attention to the CCA on the battery. 

 I went through the engine lapped the valves replaced the rings. It may be a little tight. I just went back and checked the valve adjustments and they are correct. I did look at the battery and it said 150 CCA.

The K341 on my CC 1650 also cranks stupidly hard. From what I've been told, there is a tab that can break off of the cam that will cause the ACR not to function, and there is also a spring in there that can get weak and cause the same symptom. 

 

I can only get it started with an extremely hot battery and jumper cables to another battery. 

 

You may have the same issue. What CCA is your battery?

@coldbear was referring to having too much fuel in the cylinder, this will cause the engine to turn over hard.

 The battery is at 150 CCA  i'm going back to AutoZone and get one with at least 350 

 I guess I wasn't paying attention the day I picked it up the price was good but the 

battery enough git up and go. I just think there's lots of compression here since I put new rings in it and it was bored 20 over .  If the battery doesn't do it then I may have to tear the motor back down and see what's going on with the camshaft 

 Definitely a set back

Hopefully not too much of a set back. I put a 150CCA battery on my dad's C-141 and it cranked it over about 10 revolutions before it gave out. The battery is probably your issue. It's definitely worth the extra $20 for the big battery. 

 

My C-120 has an Exide car-style battery on it. I think it's around 550 CCA. It is excellent and fits the battery tray perfect. It was on the tractor when I got it and I hope it lasts a long time. It'll cost a bit more than a mower battery when it comes time to replace.

In standard troubleshooting, the first thing I’d ask a water heater customer is “what did you last do to it”?  

 

Well.....  what did you do to it?  

[WildmanC120 613]

Check your timing too.  My c-160 is a hard cranker. It would also kick back when starting. I adjusted the points gap to .18-.19 and it made a huge difference.

16hp Kohlers need a LOT of amps at the starter turn over a fresh rebuild. 150 cca ain't gonna cut it! Hopefully, that's the problem and not in the acr.

[tom2p 2,393]

agree - regardless (of other potential issues) 

 

150 CCA not sufficient ; certainly not for a 16HP garden tractor 

 

my Diehard is 340 CCA 

 

Duracell 350 CCA 

 

( 550 CCA can be common in a car battery )

Did you check if there is gas in the cylinder yet? Hydro lock sounds likely if gas is flowing out of the carb.

Try firing a phaser into the Dilithium crystals to recharge them.

I may not be a Captain but I'm well acquainted with one.

Well I thought about starting a new thread for this one but I figured the heading was fine because now it's the end exclamation!

 Well at least for now. I had a catastrophic event yesterday with the motor running. Sounded good for the longest time then all of a sudden I heard a big clunk followed by slow slow turning of the fly wheel. I knew right away what had happened! But lo and behold I do believe the block  is OK 

 Pictures are worth 1000 words !

 Or should I say 1000 pieces !

Oh man that's awful. How the heck did it happen??? 

[Razorback 1,032]

Ouch!!!

[The Tuul Crib 7,332]

Not really sure I was told maybe the rod Was on backwards or in proper torque on the rod cap. Oil starvation. I did put the 

crank on the lathe and cleaned it up . 

 Probably have to put a mic on it to see If it is still within spec.

[richmondred01 2,221]

At minimum that will need to be polished. Most likely turned. 
hole in rod cap faces the cam. 
How does the cylinder apron look.

Many times when the rod breaks like that it cracks or chips the apron.

At a glance l havent found any damage. 

I might have gotten lucky on this one . 

I think the  ghost of lRV is with me 

for sure!

[Elliot Garfinkel 166]

Sorry to hear and see that,I guess you will start to rebuild.Is this something you  use as a worker or do you have time on this.I hope their is no further damage
