Cub Cadet with Briggs and Stratton motor

[Forest#2]

I did not see where you stated for sure it is the double throat type. (by looking at the IPL of the carbs in the link)
Both type carbs use a fuel solenoid so that cannot be used as a ID to my question.
The reason I asked which carb is being used is because I've seen different running symptoms (issues) depending on which carb is used when the carb starts going bad or when a Clone is used as a replacement.
When we ask you questions we have our reasons for such. You are our eyes so we can try to get on the same page as you when trying to help you.

I seen this statement in your post #14 is why I asked again for a confirm.
As far as the carb goes I believe it is a double based on the fuel solenoid that it has.

I have the parts break down from Briggs which is the same as the one you asked me to go to. In looking at the fuel solenoid there are 2 versions of it. One built before code date 04080400. That is the fuel solenoid my carb has which is double barrel steel bowl. The id on the carb only says Nikki R. I believe my problem is the carb I bought. It has the newer version fuel solenoid.

Chances are you are correct about a China clone replacement when they are the double throat type.
If you got it using Amazon Prime you can get a FREE return and refund for all.

Here is a link that shows some good useful info about them Nikki carbs, but usually not any need into taking a NEW clone one apart because you got one that was built bad and chance of repair is slim to none. I have taken parts out of a clone in the bowl are, o rings and jets and used into a real Nikki. Most generally no need in going into the upper part of them, just the bowl area and it's really common for the O-rings on the jets to be bad plus the upper gaskets.

Often when the key shears it damages the key ways in the flywheel or the crankshaft
Check carefully and you will probably find a lip on one edge on one of both
These will need to be removed carefully before you replace the key or the flywheel will not be able to lock onto the taper and the key will keep on sheari

Kewl thank you very much

Maybe to late for this, Keyway on the Koler should be able to fix by tig welding the chipped area. I have had success with shaft keyways, If you try, a must is to heat the shaft before welding if you do not heat the shaft it could bend. Anyone that wants more detail let me know, glad to share.

 

[bertsmobile1]

The key is just for timing so there is no need to weld & remachine
The taper does all of the work
But a very small burr will prevent the taper from locking
On more than one engine I have needed to lap the taper in with lapping paste because it was too badly scored to lock tight.

Have a B & S 23hp Intek VTwin engine that has sheered several fly wheel keys due to inproper fly wheel torque, which is150 ft.#.

Problem; without a B & S fly wheel holder, which I don't have, is there some other way to hold the fly wheel in place??

 

[Forest#2]

You ever try a nylon strap from a ratchet strap?

Just let it wrap around the flywheel several times and then secure the end and then torque the flywheel nut.

I cannot recommend the rope method on your OHV because you can bend/break warp valves. This is feeding a chunk of rope into the cylinder and then as the piston comes up it contacts the rope. I use this method with care on small 2 cycle engines. The small 2 cycles do not have valves but have to be careful and make sure none of the rope is hanging out the exhaust port or the piston can cock sideways and cause damage.

"You ever try a nylon strap from a ratchet strap"?

Have not heard or seen that, will take a look. Going to try a 12 in. pair of vice grips around the fly wheel "flange" that is around the crank shaft. Have put 1 around it and locked it down hard, doesn't look like it will move.

Will be in touch.

 

[bertsmobile1]

Very important.
Clean up the tapers, both of them nice & shinny with a wire brush
Run your thumb nail around the hole and feel for any burrs particularly around the key slots
Any burr there, even if it is as small as 0.0001" will prevent the tapers from locking and must be removed
I file the burrs with a warding file then lap the two tapers against each other with lapping paste
