Is there a way to use a larger Font (for we with vision problems)


Reference Cub Cadet LT1045, Model 13RX11CH756, Mfgr date: 06/2007

This Lawn mower runs with no problem with normal operation of the engine while mowing. Idles proper and runs at full throttle with no issues. However, after turning off the engine and let set (not running) for 20 30 minutes (usual break time) then when wanting to start again, it does not start properly either with or without applying the choke.

I have been removing the Carburetor area breather unit giving direct access to the opening to the Carburetor then spraying Carburetor Cleaner (for starter fluid) and the engine will start rather quick but seems to not pick up the gas very quick since I have to continue to give a few "short sprays" to keep engine running (for around 30 to 60 seconds) then it evidently gets a proper supply of fuel (normal gasoline from it's gas tank) and continues to run normal.

I have only limited experience and knowledge regarding the type of Fuel Pump on these Models. It of course is mounted on the Carburetor area which is at a higher level than the Gasoline source which would suggest that it does not depend on "Gravity Flow". The visible in-line unit in the gas line appears to be approximately 1/3 to 1/2 full at all times. Have never seen it full -- either running or off..

As discussed above, the Engine runs with no problems so surely this issue would not be related to lack of oxygen caused by a stopped up vent in the fuel tank cap.

All hoses and clamps appear like new. This unit is several years old but has very limited usage over these years.

Any suggestions to resolve this issue will be appreciated

When your air filter is off check to see that the choke is closing all the way.... Even a tiny gap can cause it not to work right.....

Thanks for the reply. I had already checked that before my original post -- and it was OK.
I think the issue may be related to not getting proper gas supply -- perhaps concerning the relay on bottom of the Carburetor-- may possibly be partially stuck.

It has been cool and raining here so haven't checked on this yet. Being cautious since a lot of Flus going around. I don't want to join the Doctor line -- [Grin]....

vern66, something to try (cause it is free and easy) after your break, try removing the gas cap and then putting it back on. It may not be venting correctly and causing a "vapor lock" situation. If that doesn't work I would look at replacing the fuel filter. Let us know what you find out.

If the solenoid is stuck and you start the engine with carb cleaner, etc., something has to dislodge the stuck solenoid or the engine would die shortly if it doesn't get unstuck.

But, engines vibrate and maybe this vibration is what unsticks the solenoid?

You can test this by turning the ignition key to 'on,' then lightly tapping the solenoid prior to cranking the engine. If it starts, you've found the problem.

I have checked that the Fuel Pump is functioning properly for supplying fuel.
The fuel Solenoid (on bottom of Carburetor) evidently is the reason for lack of fuel supply to the Carburetor.
It does not activate to open the gas entry to the carburetor -- when turning on Key.

I removed the Solenoid to test-- and when applying 12 volts through the contact wire (with proper ground contact for the unit) does NOT activate/energize the Solenoid to pull the "plunger" down to open the fuel port.
The "plunger" was stuck and rather difficult to move in and out but finally loosened up but continued to not function properly.

As a test, I pushed the "plunger" all the way down (OPEN) and re-installed the Solenoid. The engine started normally. In fact, I mulched leaves for an hour, turned the engine off, let set for 20 minutes; and then re-started with no issues. So obviously, the opening for gas entry to the carburetor was not stopped by the Solenoid during this test

I don't plan to purchase a new OEM Solenoid due to the excessive cost but it seems the "After Market" units are more affordable. However, each parts diagram I have found only shows the Solenoid as a part of a Carburetor unit and NOT as a separate unit. Therefore, using Google; I have not found a "definite" part number for the Solenoid on my Cub Cadet with 20 HP Kohler Engine.

Of course, I found many MANY different Solenoids but have not been able to distinguish the proper unit for this Engine. Perhaps someone on this Forum may have experience (and resources) to identify the correct part number using the information from this engine which is listed below.

Many Thanks for your reply:

I have already done this search among what seemed like 100 others, however; the response was:
Fuel Solenoid Kit Replace For Carb Kohler 2475722-S 2404120-S CV17-25 CV620-740.

My concern is that I (so far) have no way of knowing if the above indicated numbers refers to the actual part numbers for my engine or carburetor. I need to be sure that it would be a replacement for my Engine as per information in my previous post. So far, I have not found the identification (Part Number) of my original solenoid so to know if a proper replacement part id proper.

These numbers are completely different from the numbers on my Engine ID Tag (as originally listed)

I thought you would be able to find it on your own but this is the link with the exact part.

The part at the link you provided appears "visually" to be the same as my actual original part. However, the identification numbers seem to have no reference to applying to the Engine numbers I included in my post. The confusion seems to be that apparently ALL parts diagrams do not list the Solenoid as a separate item (separate part number) and is listed as part of the Carburetor units.

However, yesterday after my last post I found two different part numbers for a Solenoid that "hopefully" is a replacement unit for my engine. Those numbers are: KH-24-757-45-S and KH-12-757-33 with the last number being visually more like the original than the first. I was going to call Kohler to try to check and verify if these numbers ARE or are NOT the proper part for my engine. Today is a holiday so the call was not productive.

I think I will find an "after market" source and (since the price is nominal) go ahead and order a solenoid for the last number above. The OEM prices for these are rather expensive to the point of being almost like "legal robbery"

Thanks again for your help -- Vern....

Forgot to mention:
It appears the Solenoid malfunction is intermittent and not consistent. While the engine was running (at a normal idle) I disconnected the power connection wire and the engine stopped almost immediately -- so the coil definitely had the plunger" pulled open allowing the flow of fuel and the wire disconnect allowed the "plunger" to return in the closed upward position and shut off the fuel causing the engine to stop.

You are way over thinking this. Look at the link I gave you. It says it is for part 12 757 33-S. I, as with almost everyone on here I would not post a part that we did not know would work. We research before we post.

Perhaps I am (or have been) overly cautious regarding selecting the correct replacement part due primarily to all of my research and searching many Web Sites prior to posting my inquiry on this Forum. I am rather new to the Forums and certainly agree (with you) that most replies have been logical and helpful. However, the various searching I did trying to select the correct part was different -- especially trying to use parts diagrams that did not identify the Solenoid as an individual part. It was a part of (included in) the Carburetor. Also, there was no contact during the weekend (or holiday) to discuss with Manufacturer Support.

Evidently, I must have upset you --and-- if I have, I apologize for that. It certainly is not my intentions to do that for anyone.

Again, I appreciate your help

My Regards, Vern.....

Vern,

I am not upset I just stink at writing. I do not always come across correctly when putting types to computer screen. Not wasting money is a good thing and we as a whole try to not have people waste it. I was going to put on my last post that we are not mowing anymore so you can take a long time to get this fixed. Enjoy the learning experience. If we stop learning we are dead.:thumbsup:

I received the new Solenoid today (Sat 11-17-2018) and installed. It now works perfectly. I Mulched leaves after the replacement and it re-starts as it should with no issues. The cost delivered for the Solenoid was $11.49.

Regards to all, Vern....
