Hi.

I have a Castel Garden TC102 from 2002 fitted with a Kohler Courage 15 PS-SV470-0002.

Looking up this spec engine it appears to have been fitted to an Electrolux???

Anyway in short I’m looking for an aftermarket carb to replace the Walbro LMK currently fitted, which i’m pretty sure is the original although I cant be sure. There are plenty on ebay but part no’s differ slightly, specifically the 0002, which again seems to be the Electrolux ref.
Research from engine diagrams says carb part no's could be 20 853 23-S or 20 853 86-S, can't seem to match these. They look basically the same except on the original there is a protruding adjuster with spring which only has a half turn then a stop on the carb body. Could this be the mixture adjustment? Aftermarket ones have a hole in the same place with what looks like a recessed plug, maybe with a adjustment? difficult to see. This is the only difference that I can see.



Any ideas anyone? thanks in anticipation

Well that Spec uses the 20 853 23-S carburetor. Unfortunately it is NLA from Kohler.

You check out the 20 853 33-S used on the SV470-0108 as appear to be a gravity fed version. Probably will need to change some of the linkages.

Thanks Star Tech, when you say gravity fed you mean no fuel pump I presume?

The linkage points look the same

Correct.

It will probably turn out to be correct but I don't always trust Kohler's parts look up when it comes to carbs. Look at the number right on the carb. It will be 20 053 and two more digits. You might get lucky and find the last two digits aren't 23 but something else that's still available. I'm just picking the last two numbers at random here but for example, if you look at your carb and find the number on it is 20 053 32, the replacement carb part number would be 20 853 32-S. What ever number is on the carb you simply change the 053 to 853 and add as S to the end and you have the replacement part number. You may find some other numbers on the carb but you are looking for the number that begins with 20 053. It's a bit of a long shot but I have found more than once that the carb put on at the factory is a different part number than is actually on the engine.

For me I have to trust the dealer website for part numbers; although, ever since Kohler dump Kolher Plus for the new Italian Kolher's Partners website things have not been the same. Half the time older engines are not even on the site.

It's sort of funny. When Kohler droped PartSmart and went to Kohler PLUS, many of the dealers were upset about it and never really liked Kohler PLUS. When Kohler changed to this new system, I told one of my colleagues, "I know a lot of dealers never liked Kohler PLUS but it won't be long and they will be missing it."

my carb nos are 114-0964 2005303 which translates as 20 853 03-S ... maybe. This carb seems to relate to engine

CV14 CV15S CV16S if you go the ebay look-up route. They all look very similar but mine has a solenoid under the bowl like the 33- S which I have now ordered. Thanks for your help​

20 853 03-S supersedes to 20 853 86-S, is still available and is for a Courage single cylinder engine. If that is what ebay is saying they are incorrect. CV single cylinder carb part numbers begin with 12. See if that ebay search didn't lead you to a 12 853 03-S and not a 20 853 03-S. I've been fooled by that before.

As I say I’ve ordered a 33-S, hope its ok. Looking at all the various part nos the basic size, carb body, linkage etc look the same, so what, if anything is likely to be different internally, the jet sizes?

hi again,
i have a basic question to my initial query.
I have a model with no fuel pump. I have fitted new carb, but the petrol is not getting to it from the tank and therefore not firing/starting.
I can see the filter hasn’t got much fuel in, but the line is free of obstruction.
Is it just a case of once its going the carb sort of sucks it through
Should i add some fuel straight into the carb?

Gravity Fed is just that the fuel has to flow down and fill the carburetor from it own weight. Fuel filter can look empty at first unless you fill the line and them with fuel. You can develop an air lock if the carburetor fills before all the air in the line escapes. Sometimes this air lock can actually prevent fuel from flowing out the fuel tank; hence, a vapor lock condition.

Either fuel enters the carb by gravity flow, OR the tank is below the carb and a pump is required. Those are your ONLY 2 options.

Most mower fuel pumps work by having the crankcase pressure pulse operate a diaphragm pump. So the engine has to be running to pump any fuel. Therefore priming the carb with fuel MAY be required for the first start.

The carb is below the tank and it is gravity fed but some of the fuel hose/shut off and filter all hang below the carb so I need to fill it all somehow or somehow blow it through. Once its through I’m sure it will be fine, its just getting that first fill

If ordering aftermarket carburetor for Kohler engines in general, I have not had good luck. By that I mean runs, yet hunts and surges. In general, other than Kohler engine aftermarket carburetors, had good success.

It would just be good to get it started and running first!

Still can't keep the thing running. Replaced shut off valve and filter. Think I've got air out of the line, filter looks full. If I add petrol straight into the carb it fires up, runs briefly, sounds fine, then stops. How can I get this fuel flowing??

Is it a gravity fed tank? Take an air compressor and blow back through the lines. If a fuel pump, then take fuel line off going to carburetor, and crank the engine. Fuel should pulse/spurt out at a nice steady flow. PlanB, hook up a nurse tank to carburetor and get it running to confirm everything else is good, and then fix fuel flow issues.

If you have a carb with a solenoid on the bottom check that it fully retracts
Kohler fitted some that used the body of the solenoid as a ground connection so have a single solenoid wire
If your engine has a plastic / rubber manifold then you need a jumper fitted
On these there has to be a jumper between the carb body & the engine or the solenoid will not retract thus no fuel from the carb to the engine.
I have no access to Castle Garden IPL's so I can not check
The carb solenoid trips at 8V so you can use one of those square 9V batteries to test it

Hi again and thanks,
Took the mower round a mates with more space, fuel now reaching carb but it just fires up for a few moments then dies, sounds fine when it runs.

Now looking at spark as its very weak, almost non existent, cleaned up coilpack, took off flywheel and 2 magnets dropped off.
So re-fix magnets, test coil (replace if necc) and new plug and see where we are then.
why do you fix one thing and another appears?

Conclusion and eventual success: Changed coilpack for new (deemed useless) refixed magnets. Now starts much easier but same problem. Can keep it running but revs not high enough to engage blades and all throttle responses all very hit and miss. Replace old carb using float, inlet needle and solenoid from new carb. Now runs fine, in fact better.

I conclude and agree with above from Tiger. Maybe the problem was the numbers didn’t match entirely on the new carb but personally I think the carb wasn’t good.
Thanks for responses and here’s until the next time ... hopefully not too soon!
