Thank you for serving!

I can, the bendix is probably cruddy. Clean it up and lube it.

I had problems with my 14hp turning over hard. Found the spring on the auto compression release disengaged with the weight. This was easily repaired by removing the cam gear cover. Once I removed the cover I was able to see the spring was disengaged, and able to re-engage it with a pick set.

IMO this is a weak spot of all K series Cub Cadets.....

so I'm working on some hard start issues on my 1650. i remember during rebuild 2 springs and some levers on the cam for the compression release. thats about as much as a know about it. how do i test if my compression release is working on my engine? if it is not working what can i do to check things out while the motor is in the tractor?

I'm moving this to your other thread. No need to start a new one and have info in two places.


Take the spark plug out, roll the motor up to TDC on the compression stroke. Take a rubber tipped air hose and put up to the plug hole and lightly blow into it. Should hear air coming out the exhaust. If so, it's working. If not, roll the motor back just a few degrees and check again. Make sure it is on the COMPRESSION stroke. Otherwise, both valves will be open.

If you don't have air movement, then remove the cam cover plate. The compression mechanism will be apparent. Consult the service manual.... it covers this stuff.


Did you remove and clean the grounds as suggested?? It sounds to me like you had a ground issue as sometimes it will crank and others not.

J-mech, thanks for the move. Wasn't for sure on where to put it. I haven't had time to dig into the grounds yet. Just going over things in my mind so when I can get into it I can dive right in. It always cranks when I turn the key. Sometimes it seems to turn nice and fast and start. Sometimes it cranks over and seems to hit a wall and not want to turn over anymore. When it gets to the hard part I can sometimes cycle the key a couple times and it will crank over again. This is why I'm thinking the engine may be building compression. Guess I'll have to brush up on how to find top dead center and check my tappet clearance too while I'm at it

Checking valve adjustment is not a bad idea.... but according to you, this is a low hour engine. Unless you doubt your abilities, the valves had better still be in adjustment. CHECK THE GROUND. Don't get all hyped up, and study every single possible cause. It's not difficult to figure this out.

so i cleaned all of the grounds and it is starting like a raped ape. its had a handful of cold and hot starts and no issues. thanks for everyone keeping me on track to check the ground system out. i do see a dedicated ground wire to the starter when i come back in half a year. I'm going to try and get a yard trim in before i head out just to try everything out.

Good to hear ( read ) your Quiet Line starts! You may already know this tid bit, but on these models, I have added another ground cable from the right-top engine tin, I think its to the bearing plate, to the fire wall mount. More so between the tractor's frame and actual fire wall. This works so well, I can start my 1450 with out the main ground cable routed from the starter to the right front of the tractor frame!!!

The Quiet Line is a great garden tractor, and rightfully has it's place in the IH line up!

Have a good evening,- all!!
